Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20088, here are decompositions:

  • 17 + 20071 = 20088
  • 37 + 20051 = 20088
  • 41 + 20047 = 20088
  • 59 + 20029 = 20088
  • 67 + 20021 = 20088
  • 97 + 19991 = 20088
  • 109 + 19979 = 20088
  • 127 + 19961 = 20088

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 20088 first appears in π at position 131,536 of the decimal expansion (the 131,536ordinal-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.
