Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148658, here are decompositions:

  • 19 + 148639 = 148658
  • 31 + 148627 = 148658
  • 79 + 148579 = 148658
  • 109 + 148549 = 148658
  • 127 + 148531 = 148658
  • 157 + 148501 = 148658
  • 229 + 148429 = 148658
  • 271 + 148387 = 148658

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 148,658 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 148658 first appears in π at position 499,327 of the decimal expansion (the 499,327ordinal-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.
