Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620364, here are decompositions:

  • 5 + 31620359 = 31620364
  • 47 + 31620317 = 31620364
  • 101 + 31620263 = 31620364
  • 173 + 31620191 = 31620364
  • 197 + 31620167 = 31620364
  • 233 + 31620131 = 31620364
  • 257 + 31620107 = 31620364
  • 383 + 31619981 = 31620364

Showing the first eight; more decompositions exist.
