Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102850, here are decompositions:

  • 53 + 102797 = 102850
  • 89 + 102761 = 102850
  • 149 + 102701 = 102850
  • 173 + 102677 = 102850
  • 197 + 102653 = 102850
  • 239 + 102611 = 102850
  • 257 + 102593 = 102850
  • 263 + 102587 = 102850

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 102,850 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 102850 first appears in π at position 503,637 of the decimal expansion (the 503,637ordinal-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.
