Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148946, here are decompositions:

  • 13 + 148933 = 148946
  • 19 + 148927 = 148946
  • 73 + 148873 = 148946
  • 79 + 148867 = 148946
  • 163 + 148783 = 148946
  • 199 + 148747 = 148946
  • 223 + 148723 = 148946
  • 277 + 148669 = 148946

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 148,946 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 148946 first appears in π at position 553,203 of the decimal expansion (the 553,203ordinal-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.
