Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99888, here are decompositions:

  • 7 + 99881 = 99888
  • 11 + 99877 = 99888
  • 17 + 99871 = 99888
  • 29 + 99859 = 99888
  • 59 + 99829 = 99888
  • 71 + 99817 = 99888
  • 79 + 99809 = 99888
  • 101 + 99787 = 99888

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 99888 first appears in π at position 4,983 of the decimal expansion (the 4,983ordinal-suffix:rd 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.
