Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147483854, here are decompositions:

  • 41 + 2147483813 = 2147483854
  • 71 + 2147483783 = 2147483854
  • 311 + 2147483543 = 2147483854
  • 431 + 2147483423 = 2147483854
  • 617 + 2147483237 = 2147483854
  • 683 + 2147483171 = 2147483854
  • 821 + 2147483033 = 2147483854
  • 911 + 2147482943 = 2147483854

Showing the first eight; more decompositions exist.
