Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147587654, here are decompositions:

  • 71 + 2147587583 = 2147587654
  • 131 + 2147587523 = 2147587654
  • 137 + 2147587517 = 2147587654
  • 227 + 2147587427 = 2147587654
  • 257 + 2147587397 = 2147587654
  • 347 + 2147587307 = 2147587654
  • 431 + 2147587223 = 2147587654
  • 593 + 2147587061 = 2147587654

Showing the first eight; more decompositions exist.
