Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532944, here are decompositions:

  • 5 + 31532939 = 31532944
  • 71 + 31532873 = 31532944
  • 167 + 31532777 = 31532944
  • 251 + 31532693 = 31532944
  • 257 + 31532687 = 31532944
  • 347 + 31532597 = 31532944
  • 467 + 31532477 = 31532944
  • 683 + 31532261 = 31532944

Showing the first eight; more decompositions exist.
