Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102086, here are decompositions:

  • 7 + 102079 = 102086
  • 43 + 102043 = 102086
  • 67 + 102019 = 102086
  • 73 + 102013 = 102086
  • 109 + 101977 = 102086
  • 157 + 101929 = 102086
  • 223 + 101863 = 102086
  • 337 + 101749 = 102086

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 102,086 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 102086 first appears in π at position 410,823 of the decimal expansion (the 410,823ordinal-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.
