Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8662, here are decompositions:

  • 53 + 8609 = 8662
  • 89 + 8573 = 8662
  • 149 + 8513 = 8662
  • 233 + 8429 = 8662
  • 239 + 8423 = 8662
  • 293 + 8369 = 8662
  • 389 + 8273 = 8662
  • 419 + 8243 = 8662

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 8662 first appears in π at position 4,635 of the decimal expansion (the 4,635ordinal-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.
