Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528436, here are decompositions:

  • 3 + 31528433 = 31528436
  • 73 + 31528363 = 31528436
  • 109 + 31528327 = 31528436
  • 157 + 31528279 = 31528436
  • 223 + 31528213 = 31528436
  • 229 + 31528207 = 31528436
  • 367 + 31528069 = 31528436
  • 439 + 31527997 = 31528436

Showing the first eight; more decompositions exist.
