Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142586, here are decompositions:

  • 13 + 142573 = 142586
  • 19 + 142567 = 142586
  • 43 + 142543 = 142586
  • 229 + 142357 = 142586
  • 349 + 142237 = 142586
  • 397 + 142189 = 142586
  • 463 + 142123 = 142586
  • 487 + 142099 = 142586

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 142,586 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 142586 first appears in π at position 298,043 of the decimal expansion (the 298,043ordinal-suffix:rd 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.
