Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 124042, here are decompositions:

  • 41 + 124001 = 124042
  • 53 + 123989 = 124042
  • 59 + 123983 = 124042
  • 89 + 123953 = 124042
  • 101 + 123941 = 124042
  • 131 + 123911 = 124042
  • 179 + 123863 = 124042
  • 239 + 123803 = 124042

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 124,042 and was likely granted around 1871.

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

Position in π

The digit sequence 124042 first appears in π at position 139,307 of the decimal expansion (the 139,307ordinal-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.
