Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 181848, here are decompositions:

  • 11 + 181837 = 181848
  • 59 + 181789 = 181848
  • 61 + 181787 = 181848
  • 71 + 181777 = 181848
  • 89 + 181759 = 181848
  • 97 + 181751 = 181848
  • 109 + 181739 = 181848
  • 127 + 181721 = 181848

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 181,848 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 181848 first appears in π at position 195,932 of the decimal expansion (the 195,932ordinal-suffix:nd 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.
