Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597976, here are decompositions:

  • 43 + 31597933 = 31597976
  • 97 + 31597879 = 31597976
  • 103 + 31597873 = 31597976
  • 199 + 31597777 = 31597976
  • 283 + 31597693 = 31597976
  • 337 + 31597639 = 31597976
  • 373 + 31597603 = 31597976
  • 523 + 31597453 = 31597976

Showing the first eight; more decompositions exist.
