Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527318, here are decompositions:

  • 7 + 31527311 = 31527318
  • 41 + 31527277 = 31527318
  • 71 + 31527247 = 31527318
  • 107 + 31527211 = 31527318
  • 127 + 31527191 = 31527318
  • 167 + 31527151 = 31527318
  • 211 + 31527107 = 31527318
  • 241 + 31527077 = 31527318

Showing the first eight; more decompositions exist.
