Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20452, here are decompositions:

  • 11 + 20441 = 20452
  • 41 + 20411 = 20452
  • 53 + 20399 = 20452
  • 59 + 20393 = 20452
  • 83 + 20369 = 20452
  • 191 + 20261 = 20452
  • 233 + 20219 = 20452
  • 251 + 20201 = 20452

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 20452 first appears in π at position 51,612 of the decimal expansion (the 51,612ordinal-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.
