Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20204, here are decompositions:

  • 3 + 20201 = 20204
  • 31 + 20173 = 20204
  • 43 + 20161 = 20204
  • 61 + 20143 = 20204
  • 97 + 20107 = 20204
  • 103 + 20101 = 20204
  • 157 + 20047 = 20204
  • 181 + 20023 = 20204

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 20204 first appears in π at position 121,300 of the decimal expansion (the 121,300ordinal-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.
