Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620300, here are decompositions:

  • 31 + 31620269 = 31620300
  • 37 + 31620263 = 31620300
  • 71 + 31620229 = 31620300
  • 97 + 31620203 = 31620300
  • 109 + 31620191 = 31620300
  • 149 + 31620151 = 31620300
  • 191 + 31620109 = 31620300
  • 193 + 31620107 = 31620300

Showing the first eight; more decompositions exist.
