Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526998, here are decompositions:

  • 59 + 31526939 = 31526998
  • 71 + 31526927 = 31526998
  • 179 + 31526819 = 31526998
  • 227 + 31526771 = 31526998
  • 509 + 31526489 = 31526998
  • 521 + 31526477 = 31526998
  • 647 + 31526351 = 31526998
  • 809 + 31526189 = 31526998

Showing the first eight; more decompositions exist.
