Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23872, here are decompositions:

  • 3 + 23869 = 23872
  • 41 + 23831 = 23872
  • 53 + 23819 = 23872
  • 59 + 23813 = 23872
  • 71 + 23801 = 23872
  • 83 + 23789 = 23872
  • 131 + 23741 = 23872
  • 239 + 23633 = 23872

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 23872 first appears in π at position 21,982 of the decimal expansion (the 21,982ordinal-suffix:nd 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.
