Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147554858, here are decompositions:

  • 11 + 2147554847 = 2147554858
  • 89 + 2147554769 = 2147554858
  • 101 + 2147554757 = 2147554858
  • 131 + 2147554727 = 2147554858
  • 359 + 2147554499 = 2147554858
  • 461 + 2147554397 = 2147554858
  • 467 + 2147554391 = 2147554858
  • 557 + 2147554301 = 2147554858

Showing the first eight; more decompositions exist.
