Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532116, here are decompositions:

  • 3 + 31532113 = 31532116
  • 53 + 31532063 = 31532116
  • 113 + 31532003 = 31532116
  • 149 + 31531967 = 31532116
  • 233 + 31531883 = 31532116
  • 389 + 31531727 = 31532116
  • 449 + 31531667 = 31532116
  • 467 + 31531649 = 31532116

Showing the first eight; more decompositions exist.
