Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148508, here are decompositions:

  • 7 + 148501 = 148508
  • 37 + 148471 = 148508
  • 79 + 148429 = 148508
  • 97 + 148411 = 148508
  • 109 + 148399 = 148508
  • 127 + 148381 = 148508
  • 229 + 148279 = 148508
  • 307 + 148201 = 148508

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 148,508 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 148508 first appears in π at position 249,668 of the decimal expansion (the 249,668ordinal-suffix:th 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.
