Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102988, here are decompositions:

  • 5 + 102983 = 102988
  • 59 + 102929 = 102988
  • 107 + 102881 = 102988
  • 191 + 102797 = 102988
  • 227 + 102761 = 102988
  • 311 + 102677 = 102988
  • 401 + 102587 = 102988
  • 449 + 102539 = 102988

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 102,988 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 102988 first appears in π at position 476,870 of the decimal expansion (the 476,870ordinal-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.
