Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616570, here are decompositions:

  • 31 + 31616539 = 31616570
  • 61 + 31616509 = 31616570
  • 151 + 31616419 = 31616570
  • 211 + 31616359 = 31616570
  • 283 + 31616287 = 31616570
  • 313 + 31616257 = 31616570
  • 397 + 31616173 = 31616570
  • 421 + 31616149 = 31616570

Showing the first eight; more decompositions exist.
