Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462570, here are decompositions:

  • 17 + 31462553 = 31462570
  • 23 + 31462547 = 31462570
  • 89 + 31462481 = 31462570
  • 131 + 31462439 = 31462570
  • 137 + 31462433 = 31462570
  • 197 + 31462373 = 31462570
  • 257 + 31462313 = 31462570
  • 281 + 31462289 = 31462570

Showing the first eight; more decompositions exist.
