Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525016, here are decompositions:

  • 79 + 31524937 = 31525016
  • 223 + 31524793 = 31525016
  • 373 + 31524643 = 31525016
  • 409 + 31524607 = 31525016
  • 499 + 31524517 = 31525016
  • 547 + 31524469 = 31525016
  • 613 + 31524403 = 31525016
  • 673 + 31524343 = 31525016

Showing the first eight; more decompositions exist.
