Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512142, here are decompositions:

  • 5 + 512137 = 512142
  • 41 + 512101 = 512142
  • 83 + 512059 = 512142
  • 131 + 512011 = 512142
  • 151 + 511991 = 512142
  • 179 + 511963 = 512142
  • 181 + 511961 = 512142
  • 233 + 511909 = 512142

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 512,142 and was likely granted around 1893.

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

Position in π

The digit sequence 512142 first appears in π at position 281,513 of the decimal expansion (the 281,513ordinal-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.
