Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482880, here are decompositions:

  • 41 + 31482839 = 31482880
  • 47 + 31482833 = 31482880
  • 59 + 31482821 = 31482880
  • 101 + 31482779 = 31482880
  • 137 + 31482743 = 31482880
  • 173 + 31482707 = 31482880
  • 197 + 31482683 = 31482880
  • 239 + 31482641 = 31482880

Showing the first eight; more decompositions exist.
