Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20112, here are decompositions:

  • 5 + 20107 = 20112
  • 11 + 20101 = 20112
  • 23 + 20089 = 20112
  • 41 + 20071 = 20112
  • 61 + 20051 = 20112
  • 83 + 20029 = 20112
  • 89 + 20023 = 20112
  • 101 + 20011 = 20112

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 20112 first appears in π at position 57,981 of the decimal expansion (the 57,981ordinal-suffix:st 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.
