Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527314, here are decompositions:

  • 3 + 31527311 = 31527314
  • 37 + 31527277 = 31527314
  • 61 + 31527253 = 31527314
  • 67 + 31527247 = 31527314
  • 103 + 31527211 = 31527314
  • 157 + 31527157 = 31527314
  • 163 + 31527151 = 31527314
  • 373 + 31526941 = 31527314

Showing the first eight; more decompositions exist.
