Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71670, here are decompositions:

  • 7 + 71663 = 71670
  • 23 + 71647 = 71670
  • 37 + 71633 = 71670
  • 73 + 71597 = 71670
  • 101 + 71569 = 71670
  • 107 + 71563 = 71670
  • 167 + 71503 = 71670
  • 191 + 71479 = 71670

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 71670 first appears in π at position 25,264 of the decimal expansion (the 25,264ordinal-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.
