Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20328, here are decompositions:

  • 5 + 20323 = 20328
  • 31 + 20297 = 20328
  • 41 + 20287 = 20328
  • 59 + 20269 = 20328
  • 67 + 20261 = 20328
  • 79 + 20249 = 20328
  • 97 + 20231 = 20328
  • 109 + 20219 = 20328

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 20328 first appears in π at position 90,431 of the decimal expansion (the 90,431ordinal-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.
