Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971788, here are decompositions:

  • 5 + 971783 = 971788
  • 29 + 971759 = 971788
  • 89 + 971699 = 971788
  • 137 + 971651 = 971788
  • 149 + 971639 = 971788
  • 197 + 971591 = 971788
  • 227 + 971561 = 971788
  • 239 + 971549 = 971788

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 971,788 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 971788 first appears in π at position 899,124 of the decimal expansion (the 899,124ordinal-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.
