Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139562, here are decompositions:

  • 61 + 139501 = 139562
  • 79 + 139483 = 139562
  • 103 + 139459 = 139562
  • 139 + 139423 = 139562
  • 193 + 139369 = 139562
  • 223 + 139339 = 139562
  • 229 + 139333 = 139562
  • 271 + 139291 = 139562

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 139,562 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 139562 first appears in π at position 852,000 of the decimal expansion (the 852,000ordinal-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.
