Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998144, here are decompositions:

  • 61 + 998083 = 998144
  • 67 + 998077 = 998144
  • 73 + 998071 = 998144
  • 127 + 998017 = 998144
  • 181 + 997963 = 998144
  • 211 + 997933 = 998144
  • 331 + 997813 = 998144
  • 337 + 997807 = 998144

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 998,144 and was likely granted around 1911.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 998144 first appears in π at position 213,730 of the decimal expansion (the 213,730ordinal-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.
