Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009142, here are decompositions:

  • 3 + 1009139 = 1009142
  • 151 + 1008991 = 1009142
  • 163 + 1008979 = 1009142
  • 229 + 1008913 = 1009142
  • 241 + 1008901 = 1009142
  • 271 + 1008871 = 1009142
  • 283 + 1008859 = 1009142
  • 313 + 1008829 = 1009142

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 1,009,142 and was likely granted around 1911.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 1009142 first appears in π at position 973,748 of the decimal expansion (the 973,748ordinal-suffix:th digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
