Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1886, here are decompositions:

  • 7 + 1879 = 1886
  • 13 + 1873 = 1886
  • 19 + 1867 = 1886
  • 97 + 1789 = 1886
  • 103 + 1783 = 1886
  • 109 + 1777 = 1886
  • 127 + 1759 = 1886
  • 139 + 1747 = 1886

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 1886 first appears in π at position 42,955 of the decimal expansion (the 42,955ordinal-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.
