Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479416, here are decompositions:

  • 79 + 31479337 = 31479416
  • 109 + 31479307 = 31479416
  • 127 + 31479289 = 31479416
  • 139 + 31479277 = 31479416
  • 433 + 31478983 = 31479416
  • 457 + 31478959 = 31479416
  • 769 + 31478647 = 31479416
  • 823 + 31478593 = 31479416

Showing the first eight; more decompositions exist.
