Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620328, here are decompositions:

  • 11 + 31620317 = 31620328
  • 29 + 31620299 = 31620328
  • 59 + 31620269 = 31620328
  • 137 + 31620191 = 31620328
  • 197 + 31620131 = 31620328
  • 269 + 31620059 = 31620328
  • 347 + 31619981 = 31620328
  • 479 + 31619849 = 31620328

Showing the first eight; more decompositions exist.
