Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102680, here are decompositions:

  • 3 + 102677 = 102680
  • 7 + 102673 = 102680
  • 13 + 102667 = 102680
  • 37 + 102643 = 102680
  • 73 + 102607 = 102680
  • 157 + 102523 = 102680
  • 181 + 102499 = 102680
  • 199 + 102481 = 102680

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 102,680 and was likely granted around 1870.

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

Position in π

The digit sequence 102680 first appears in π at position 168,486 of the decimal expansion (the 168,486ordinal-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.
