Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535944, here are decompositions:

  • 3 + 31535941 = 31535944
  • 5 + 31535939 = 31535944
  • 113 + 31535831 = 31535944
  • 191 + 31535753 = 31535944
  • 197 + 31535747 = 31535944
  • 227 + 31535717 = 31535944
  • 263 + 31535681 = 31535944
  • 311 + 31535633 = 31535944

Showing the first eight; more decompositions exist.
