Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487958, here are decompositions:

  • 61 + 487897 = 487958
  • 67 + 487891 = 487958
  • 127 + 487831 = 487958
  • 139 + 487819 = 487958
  • 241 + 487717 = 487958
  • 277 + 487681 = 487958
  • 307 + 487651 = 487958
  • 397 + 487561 = 487958

Showing the first eight; more decompositions exist.
