Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508932, here are decompositions:

  • 11 + 31508921 = 31508932
  • 89 + 31508843 = 31508932
  • 251 + 31508681 = 31508932
  • 281 + 31508651 = 31508932
  • 293 + 31508639 = 31508932
  • 311 + 31508621 = 31508932
  • 353 + 31508579 = 31508932
  • 383 + 31508549 = 31508932

Showing the first eight; more decompositions exist.
