Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147472798, here are decompositions:

  • 11 + 2147472787 = 2147472798
  • 41 + 2147472757 = 2147472798
  • 47 + 2147472751 = 2147472798
  • 101 + 2147472697 = 2147472798
  • 109 + 2147472689 = 2147472798
  • 139 + 2147472659 = 2147472798
  • 181 + 2147472617 = 2147472798
  • 197 + 2147472601 = 2147472798

Showing the first eight; more decompositions exist.
