Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2758, here are decompositions:

  • 5 + 2753 = 2758
  • 17 + 2741 = 2758
  • 29 + 2729 = 2758
  • 47 + 2711 = 2758
  • 59 + 2699 = 2758
  • 71 + 2687 = 2758
  • 101 + 2657 = 2758
  • 137 + 2621 = 2758

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 2758 first appears in π at position 9,947 of the decimal expansion (the 9,947ordinal-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.
