Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4842, here are decompositions:

  • 11 + 4831 = 4842
  • 29 + 4813 = 4842
  • 41 + 4801 = 4842
  • 43 + 4799 = 4842
  • 53 + 4789 = 4842
  • 59 + 4783 = 4842
  • 83 + 4759 = 4842
  • 109 + 4733 = 4842

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 4842 first appears in π at position 7,313 of the decimal expansion (the 7,313ordinal-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.
