Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524418, here are decompositions:

  • 251 + 31524167 = 31524418
  • 257 + 31524161 = 31524418
  • 311 + 31524107 = 31524418
  • 479 + 31523939 = 31524418
  • 617 + 31523801 = 31524418
  • 839 + 31523579 = 31524418
  • 881 + 31523537 = 31524418
  • 941 + 31523477 = 31524418

Showing the first eight; more decompositions exist.
