Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625984, here are decompositions:

  • 3 + 31625981 = 31625984
  • 31 + 31625953 = 31625984
  • 67 + 31625917 = 31625984
  • 73 + 31625911 = 31625984
  • 163 + 31625821 = 31625984
  • 211 + 31625773 = 31625984
  • 223 + 31625761 = 31625984
  • 331 + 31625653 = 31625984

Showing the first eight; more decompositions exist.
