Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64700, here are decompositions:

  • 7 + 64693 = 64700
  • 37 + 64663 = 64700
  • 67 + 64633 = 64700
  • 73 + 64627 = 64700
  • 79 + 64621 = 64700
  • 109 + 64591 = 64700
  • 211 + 64489 = 64700
  • 367 + 64333 = 64700

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 64700 first appears in π at position 59,047 of the decimal expansion (the 59,047ordinal-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.
