Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544436, here are decompositions:

  • 19 + 31544417 = 31544436
  • 43 + 31544393 = 31544436
  • 73 + 31544363 = 31544436
  • 89 + 31544347 = 31544436
  • 113 + 31544323 = 31544436
  • 139 + 31544297 = 31544436
  • 223 + 31544213 = 31544436
  • 229 + 31544207 = 31544436

Showing the first eight; more decompositions exist.
