Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102470, here are decompositions:

  • 19 + 102451 = 102470
  • 37 + 102433 = 102470
  • 61 + 102409 = 102470
  • 73 + 102397 = 102470
  • 103 + 102367 = 102470
  • 211 + 102259 = 102470
  • 229 + 102241 = 102470
  • 241 + 102229 = 102470

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 102,470 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 102470 first appears in π at position 60,393 of the decimal expansion (the 60,393ordinal-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.
