Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546570, here are decompositions:

  • 17 + 31546553 = 31546570
  • 101 + 31546469 = 31546570
  • 113 + 31546457 = 31546570
  • 149 + 31546421 = 31546570
  • 233 + 31546337 = 31546570
  • 269 + 31546301 = 31546570
  • 353 + 31546217 = 31546570
  • 383 + 31546187 = 31546570

Showing the first eight; more decompositions exist.
