Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12576, here are decompositions:

  • 7 + 12569 = 12576
  • 23 + 12553 = 12576
  • 29 + 12547 = 12576
  • 37 + 12539 = 12576
  • 59 + 12517 = 12576
  • 73 + 12503 = 12576
  • 79 + 12497 = 12576
  • 89 + 12487 = 12576

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 12576 first appears in π at position 265,705 of the decimal expansion (the 265,705ordinal-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.
