Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148190, here are decompositions:

  • 19 + 148171 = 148190
  • 37 + 148153 = 148190
  • 43 + 148147 = 148190
  • 67 + 148123 = 148190
  • 127 + 148063 = 148190
  • 193 + 147997 = 148190
  • 241 + 147949 = 148190
  • 271 + 147919 = 148190

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 148,190 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 148190 first appears in π at position 68,953 of the decimal expansion (the 68,953ordinal-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.
