Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479646, here are decompositions:

  • 53 + 31479593 = 31479646
  • 89 + 31479557 = 31479646
  • 179 + 31479467 = 31479646
  • 227 + 31479419 = 31479646
  • 347 + 31479299 = 31479646
  • 449 + 31479197 = 31479646
  • 563 + 31479083 = 31479646
  • 677 + 31478969 = 31479646

Showing the first eight; more decompositions exist.
