Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148866, here are decompositions:

  • 5 + 148861 = 148866
  • 7 + 148859 = 148866
  • 13 + 148853 = 148866
  • 37 + 148829 = 148866
  • 73 + 148793 = 148866
  • 83 + 148783 = 148866
  • 103 + 148763 = 148866
  • 139 + 148727 = 148866

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 148,866 and was likely granted around 1873.

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

Position in π

The digit sequence 148866 first appears in π at position 327,193 of the decimal expansion (the 327,193ordinal-suffix:rd 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.
