Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616456, here are decompositions:

  • 37 + 31616419 = 31616456
  • 97 + 31616359 = 31616456
  • 199 + 31616257 = 31616456
  • 283 + 31616173 = 31616456
  • 307 + 31616149 = 31616456
  • 397 + 31616059 = 31616456
  • 409 + 31616047 = 31616456
  • 433 + 31616023 = 31616456

Showing the first eight; more decompositions exist.
