Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616210, here are decompositions:

  • 37 + 31616173 = 31616210
  • 61 + 31616149 = 31616210
  • 97 + 31616113 = 31616210
  • 151 + 31616059 = 31616210
  • 163 + 31616047 = 31616210
  • 193 + 31616017 = 31616210
  • 211 + 31615999 = 31616210
  • 499 + 31615711 = 31616210

Showing the first eight; more decompositions exist.
