Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 35728, here are decompositions:

  • 131 + 35597 = 35728
  • 137 + 35591 = 35728
  • 191 + 35537 = 35728
  • 197 + 35531 = 35728
  • 281 + 35447 = 35728
  • 347 + 35381 = 35728
  • 389 + 35339 = 35728
  • 401 + 35327 = 35728

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 35728 first appears in π at position 18,419 of the decimal expansion (the 18,419ordinal-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.
