Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20330, here are decompositions:

  • 3 + 20327 = 20330
  • 7 + 20323 = 20330
  • 43 + 20287 = 20330
  • 61 + 20269 = 20330
  • 97 + 20233 = 20330
  • 157 + 20173 = 20330
  • 181 + 20149 = 20330
  • 223 + 20107 = 20330

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 20330 first appears in π at position 3,831 of the decimal expansion (the 3,831ordinal-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.
