Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468578, here are decompositions:

  • 41 + 2147468537 = 2147468578
  • 71 + 2147468507 = 2147468578
  • 149 + 2147468429 = 2147468578
  • 347 + 2147468231 = 2147468578
  • 389 + 2147468189 = 2147468578
  • 509 + 2147468069 = 2147468578
  • 659 + 2147467919 = 2147468578
  • 809 + 2147467769 = 2147468578

Showing the first eight; more decompositions exist.
