Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489042, here are decompositions:

  • 23 + 489019 = 489042
  • 31 + 489011 = 489042
  • 41 + 489001 = 489042
  • 61 + 488981 = 489042
  • 83 + 488959 = 489042
  • 149 + 488893 = 489042
  • 163 + 488879 = 489042
  • 181 + 488861 = 489042

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 489,042 and was likely granted around 1892.

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

Position in π

The digit sequence 489042 first appears in π at position 641,264 of the decimal expansion (the 641,264ordinal-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.
