Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500608, here are decompositions:

  • 19 + 31500589 = 31500608
  • 79 + 31500529 = 31500608
  • 151 + 31500457 = 31500608
  • 157 + 31500451 = 31500608
  • 229 + 31500379 = 31500608
  • 241 + 31500367 = 31500608
  • 421 + 31500187 = 31500608
  • 619 + 31499989 = 31500608

Showing the first eight; more decompositions exist.
