Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4890, here are decompositions:

  • 13 + 4877 = 4890
  • 19 + 4871 = 4890
  • 29 + 4861 = 4890
  • 59 + 4831 = 4890
  • 73 + 4817 = 4890
  • 89 + 4801 = 4890
  • 97 + 4793 = 4890
  • 101 + 4789 = 4890

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 4890 first appears in π at position 4,456 of the decimal expansion (the 4,456ordinal-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.
