Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18792, here are decompositions:

  • 5 + 18787 = 18792
  • 19 + 18773 = 18792
  • 43 + 18749 = 18792
  • 61 + 18731 = 18792
  • 73 + 18719 = 18792
  • 79 + 18713 = 18792
  • 101 + 18691 = 18792
  • 113 + 18679 = 18792

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 18792 first appears in π at position 7,320 of the decimal expansion (the 7,320ordinal-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.
