Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497798, here are decompositions:

29 + 2147497769 = 2147497798
41 + 2147497757 = 2147497798
101 + 2147497697 = 2147497798
107 + 2147497691 = 2147497798
137 + 2147497661 = 2147497798
227 + 2147497571 = 2147497798
239 + 2147497559 = 2147497798
317 + 2147497481 = 2147497798

Showing the first eight; more decompositions exist.
