Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 972728, here are decompositions:

  • 7 + 972721 = 972728
  • 67 + 972661 = 972728
  • 79 + 972649 = 972728
  • 151 + 972577 = 972728
  • 409 + 972319 = 972728
  • 457 + 972271 = 972728
  • 499 + 972229 = 972728
  • 607 + 972121 = 972728

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 972,728 and was likely granted around 1910.

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

Position in π

The digit sequence 972728 first appears in π at position 346,568 of the decimal expansion (the 346,568ordinal-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.
