Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617274, here are decompositions:

  • 5 + 31617269 = 31617274
  • 23 + 31617251 = 31617274
  • 107 + 31617167 = 31617274
  • 173 + 31617101 = 31617274
  • 197 + 31617077 = 31617274
  • 251 + 31617023 = 31617274
  • 263 + 31617011 = 31617274
  • 383 + 31616891 = 31617274

Showing the first eight; more decompositions exist.
