Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547232, here are decompositions:

  • 23 + 31547209 = 31547232
  • 29 + 31547203 = 31547232
  • 71 + 31547161 = 31547232
  • 89 + 31547143 = 31547232
  • 103 + 31547129 = 31547232
  • 131 + 31547101 = 31547232
  • 139 + 31547093 = 31547232
  • 193 + 31547039 = 31547232

Showing the first eight; more decompositions exist.
