Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1070, here are decompositions:

  • 7 + 1063 = 1070
  • 19 + 1051 = 1070
  • 31 + 1039 = 1070
  • 37 + 1033 = 1070
  • 61 + 1009 = 1070
  • 73 + 997 = 1070
  • 79 + 991 = 1070
  • 103 + 967 = 1070

Showing the first eight; more decompositions exist.

Banks operate many routing numbers per state and division; an unmatched checksum-valid number can still be a real RTN at a smaller institution.

Position in π

The digit sequence 1070 first appears in π at position 18,424 of the decimal expansion (the 18,424ordinal-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.
