Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102198, here are decompositions:

  • 7 + 102191 = 102198
  • 17 + 102181 = 102198
  • 37 + 102161 = 102198
  • 59 + 102139 = 102198
  • 97 + 102101 = 102198
  • 127 + 102071 = 102198
  • 137 + 102061 = 102198
  • 139 + 102059 = 102198

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 102,198 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 102198 first appears in π at position 498,158 of the decimal expansion (the 498,158ordinal-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.
