Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526558, here are decompositions:

  • 31 + 31526527 = 31526558
  • 61 + 31526497 = 31526558
  • 127 + 31526431 = 31526558
  • 139 + 31526419 = 31526558
  • 199 + 31526359 = 31526558
  • 241 + 31526317 = 31526558
  • 277 + 31526281 = 31526558
  • 331 + 31526227 = 31526558

Showing the first eight; more decompositions exist.
