Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19198, here are decompositions:

  • 17 + 19181 = 19198
  • 41 + 19157 = 19198
  • 59 + 19139 = 19198
  • 167 + 19031 = 19198
  • 197 + 19001 = 19198
  • 239 + 18959 = 19198
  • 251 + 18947 = 19198
  • 281 + 18917 = 19198

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.
