Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620584, here are decompositions:

  • 3 + 31620581 = 31620584
  • 7 + 31620577 = 31620584
  • 13 + 31620571 = 31620584
  • 67 + 31620517 = 31620584
  • 97 + 31620487 = 31620584
  • 103 + 31620481 = 31620584
  • 241 + 31620343 = 31620584
  • 283 + 31620301 = 31620584

Showing the first eight; more decompositions exist.
