Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484288, here are decompositions:

  • 7 + 31484281 = 31484288
  • 79 + 31484209 = 31484288
  • 109 + 31484179 = 31484288
  • 127 + 31484161 = 31484288
  • 229 + 31484059 = 31484288
  • 307 + 31483981 = 31484288
  • 331 + 31483957 = 31484288
  • 487 + 31483801 = 31484288

Showing the first eight; more decompositions exist.
