Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101018, here are decompositions:

  • 19 + 100999 = 101018
  • 31 + 100987 = 101018
  • 37 + 100981 = 101018
  • 61 + 100957 = 101018
  • 271 + 100747 = 101018
  • 277 + 100741 = 101018
  • 349 + 100669 = 101018
  • 397 + 100621 = 101018

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 101,018 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 101018 first appears in π at position 839,220 of the decimal expansion (the 839,220ordinal-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.
