Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938432, here are decompositions:

  • 73 + 938359 = 938432
  • 109 + 938323 = 938432
  • 139 + 938293 = 938432
  • 181 + 938251 = 938432
  • 199 + 938233 = 938432
  • 349 + 938083 = 938432
  • 373 + 938059 = 938432
  • 379 + 938053 = 938432

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 938,432 and was likely granted around 1909.

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

Position in π

The digit sequence 938432 first appears in π at position 529,179 of the decimal expansion (the 529,179ordinal-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.
