Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20432, here are decompositions:

  • 43 + 20389 = 20432
  • 73 + 20359 = 20432
  • 79 + 20353 = 20432
  • 109 + 20323 = 20432
  • 163 + 20269 = 20432
  • 199 + 20233 = 20432
  • 271 + 20161 = 20432
  • 283 + 20149 = 20432

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 20432 first appears in π at position 64,942 of the decimal expansion (the 64,942ordinal-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.
