Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9988, here are decompositions:

  • 47 + 9941 = 9988
  • 59 + 9929 = 9988
  • 101 + 9887 = 9988
  • 131 + 9857 = 9988
  • 137 + 9851 = 9988
  • 149 + 9839 = 9988
  • 197 + 9791 = 9988
  • 239 + 9749 = 9988

Showing the first eight; more decompositions exist.

Possible US bank routing number

This passes the ABA routing number checksum and matches the Federal Reserve numbering scheme.
