Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547214, here are decompositions:

  • 5 + 31547209 = 31547214
  • 11 + 31547203 = 31547214
  • 37 + 31547177 = 31547214
  • 53 + 31547161 = 31547214
  • 67 + 31547147 = 31547214
  • 71 + 31547143 = 31547214
  • 113 + 31547101 = 31547214
  • 137 + 31547077 = 31547214

Showing the first eight; more decompositions exist.
