Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489138, here are decompositions:

  • 5 + 489133 = 489138
  • 11 + 489127 = 489138
  • 29 + 489109 = 489138
  • 37 + 489101 = 489138
  • 127 + 489011 = 489138
  • 137 + 489001 = 489138
  • 157 + 488981 = 489138
  • 179 + 488959 = 489138

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 489,138 and was likely granted around 1892.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 489138 first appears in π at position 259,472 of the decimal expansion (the 259,472ordinal-suffix:nd 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.
