Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42026, here are decompositions:

  • 3 + 42023 = 42026
  • 7 + 42019 = 42026
  • 13 + 42013 = 42026
  • 43 + 41983 = 42026
  • 67 + 41959 = 42026
  • 73 + 41953 = 42026
  • 79 + 41947 = 42026
  • 139 + 41887 = 42026

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.
