Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31557336, here are decompositions:

  • 7 + 31557329 = 31557336
  • 43 + 31557293 = 31557336
  • 53 + 31557283 = 31557336
  • 59 + 31557277 = 31557336
  • 89 + 31557247 = 31557336
  • 137 + 31557199 = 31557336
  • 149 + 31557187 = 31557336
  • 157 + 31557179 = 31557336

Showing the first eight; more decompositions exist.
