Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142898, here are decompositions:

  • 31 + 142867 = 142898
  • 61 + 142837 = 142898
  • 109 + 142789 = 142898
  • 127 + 142771 = 142898
  • 139 + 142759 = 142898
  • 199 + 142699 = 142898
  • 241 + 142657 = 142898
  • 307 + 142591 = 142898

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 142,898 and was likely granted around 1872.

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

Position in π

The digit sequence 142898 first appears in π at position 797,309 of the decimal expansion (the 797,309ordinal-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.
