Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148898, here are decompositions:

  • 7 + 148891 = 148898
  • 31 + 148867 = 148898
  • 37 + 148861 = 148898
  • 151 + 148747 = 148898
  • 229 + 148669 = 148898
  • 271 + 148627 = 148898
  • 349 + 148549 = 148898
  • 367 + 148531 = 148898

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 148,898 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 148898 first appears in π at position 776,084 of the decimal expansion (the 776,084ordinal-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.
