Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576162, here are decompositions:

  • 41 + 31576121 = 31576162
  • 71 + 31576091 = 31576162
  • 113 + 31576049 = 31576162
  • 131 + 31576031 = 31576162
  • 239 + 31575923 = 31576162
  • 263 + 31575899 = 31576162
  • 269 + 31575893 = 31576162
  • 281 + 31575881 = 31576162

Showing the first eight; more decompositions exist.
