Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20304, here are decompositions:

  • 7 + 20297 = 20304
  • 17 + 20287 = 20304
  • 43 + 20261 = 20304
  • 71 + 20233 = 20304
  • 73 + 20231 = 20304
  • 103 + 20201 = 20304
  • 127 + 20177 = 20304
  • 131 + 20173 = 20304

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 20304 first appears in π at position 171,443 of the decimal expansion (the 171,443ordinal-suffix:rd 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.
