Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524806, here are decompositions:

  • 13 + 31524793 = 31524806
  • 43 + 31524763 = 31524806
  • 163 + 31524643 = 31524806
  • 199 + 31524607 = 31524806
  • 283 + 31524523 = 31524806
  • 307 + 31524499 = 31524806
  • 337 + 31524469 = 31524806
  • 463 + 31524343 = 31524806

Showing the first eight; more decompositions exist.
