Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38430, here are decompositions:

  • 37 + 38393 = 38430
  • 53 + 38377 = 38430
  • 59 + 38371 = 38430
  • 79 + 38351 = 38430
  • 97 + 38333 = 38430
  • 101 + 38329 = 38430
  • 103 + 38327 = 38430
  • 109 + 38321 = 38430

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 38430 first appears in π at position 377,563 of the decimal expansion (the 377,563ordinal-suffix:rd 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.
