Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452864, here are decompositions:

  • 5 + 31452859 = 31452864
  • 13 + 31452851 = 31452864
  • 61 + 31452803 = 31452864
  • 71 + 31452793 = 31452864
  • 101 + 31452763 = 31452864
  • 137 + 31452727 = 31452864
  • 181 + 31452683 = 31452864
  • 197 + 31452667 = 31452864

Showing the first eight; more decompositions exist.
