Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148700, here are decompositions:

  • 7 + 148693 = 148700
  • 31 + 148669 = 148700
  • 37 + 148663 = 148700
  • 61 + 148639 = 148700
  • 67 + 148633 = 148700
  • 73 + 148627 = 148700
  • 127 + 148573 = 148700
  • 151 + 148549 = 148700

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 148,700 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 148700 first appears in π at position 275,501 of the decimal expansion (the 275,501ordinal-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.
