Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27658, here are decompositions:

  • 5 + 27653 = 27658
  • 11 + 27647 = 27658
  • 41 + 27617 = 27658
  • 47 + 27611 = 27658
  • 107 + 27551 = 27658
  • 131 + 27527 = 27658
  • 149 + 27509 = 27658
  • 179 + 27479 = 27658

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 27658 first appears in π at position 8,548 of the decimal expansion (the 8,548ordinal-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.
