Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27684, here are decompositions:

  • 11 + 27673 = 27684
  • 31 + 27653 = 27684
  • 37 + 27647 = 27684
  • 53 + 27631 = 27684
  • 67 + 27617 = 27684
  • 73 + 27611 = 27684
  • 101 + 27583 = 27684
  • 103 + 27581 = 27684

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 27684 first appears in π at position 98,717 of the decimal expansion (the 98,717ordinal-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.
