Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616804, here are decompositions:

  • 31 + 31616773 = 31616804
  • 97 + 31616707 = 31616804
  • 127 + 31616677 = 31616804
  • 157 + 31616647 = 31616804
  • 181 + 31616623 = 31616804
  • 283 + 31616521 = 31616804
  • 523 + 31616281 = 31616804
  • 547 + 31616257 = 31616804

Showing the first eight; more decompositions exist.
