Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20952, here are decompositions:

  • 5 + 20947 = 20952
  • 13 + 20939 = 20952
  • 23 + 20929 = 20952
  • 31 + 20921 = 20952
  • 53 + 20899 = 20952
  • 73 + 20879 = 20952
  • 79 + 20873 = 20952
  • 103 + 20849 = 20952

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 20952 first appears in π at position 63,772 of the decimal expansion (the 63,772ordinal-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.
