Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 182988, here are decompositions:

  • 7 + 182981 = 182988
  • 19 + 182969 = 182988
  • 31 + 182957 = 182988
  • 59 + 182929 = 182988
  • 61 + 182927 = 182988
  • 67 + 182921 = 182988
  • 89 + 182899 = 182988
  • 101 + 182887 = 182988

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 182,988 and was likely granted around 1875.

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

Position in π

The digit sequence 182988 first appears in π at position 108,221 of the decimal expansion (the 108,221ordinal-suffix:st 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.
