Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 24872, here are decompositions:

  • 13 + 24859 = 24872
  • 31 + 24841 = 24872
  • 73 + 24799 = 24872
  • 79 + 24793 = 24872
  • 109 + 24763 = 24872
  • 139 + 24733 = 24872
  • 163 + 24709 = 24872
  • 181 + 24691 = 24872

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 24872 first appears in π at position 181,870 of the decimal expansion (the 181,870ordinal-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.
