Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31551336, here are decompositions:

  • 7 + 31551329 = 31551336
  • 17 + 31551319 = 31551336
  • 29 + 31551307 = 31551336
  • 53 + 31551283 = 31551336
  • 59 + 31551277 = 31551336
  • 149 + 31551187 = 31551336
  • 163 + 31551173 = 31551336
  • 197 + 31551139 = 31551336

Showing the first eight; more decompositions exist.
