Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528570, here are decompositions:

  • 11 + 31528559 = 31528570
  • 23 + 31528547 = 31528570
  • 71 + 31528499 = 31528570
  • 137 + 31528433 = 31528570
  • 197 + 31528373 = 31528570
  • 233 + 31528337 = 31528570
  • 257 + 31528313 = 31528570
  • 401 + 31528169 = 31528570

Showing the first eight; more decompositions exist.
