Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468216, here are decompositions:

  • 43 + 2147468173 = 2147468216
  • 97 + 2147468119 = 2147468216
  • 457 + 2147467759 = 2147468216
  • 499 + 2147467717 = 2147468216
  • 547 + 2147467669 = 2147468216
  • 577 + 2147467639 = 2147468216
  • 823 + 2147467393 = 2147468216
  • 877 + 2147467339 = 2147468216

Showing the first eight; more decompositions exist.
