Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4538, here are decompositions:

  • 19 + 4519 = 4538
  • 31 + 4507 = 4538
  • 97 + 4441 = 4538
  • 181 + 4357 = 4538
  • 199 + 4339 = 4538
  • 211 + 4327 = 4538
  • 241 + 4297 = 4538
  • 277 + 4261 = 4538

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 4538 first appears in π at position 16,838 of the decimal expansion (the 16,838ordinal-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.
