Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488138, here are decompositions:

  • 19 + 488119 = 488138
  • 127 + 488011 = 488138
  • 241 + 487897 = 488138
  • 307 + 487831 = 488138
  • 349 + 487789 = 488138
  • 397 + 487741 = 488138
  • 421 + 487717 = 488138
  • 457 + 487681 = 488138

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 488,138 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 488138 first appears in π at position 207,856 of the decimal expansion (the 207,856ordinal-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.
