Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498420, here are decompositions:

  • 53 + 31498367 = 31498420
  • 71 + 31498349 = 31498420
  • 113 + 31498307 = 31498420
  • 131 + 31498289 = 31498420
  • 167 + 31498253 = 31498420
  • 227 + 31498193 = 31498420
  • 269 + 31498151 = 31498420
  • 479 + 31497941 = 31498420

Showing the first eight; more decompositions exist.
