Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147493518, here are decompositions:

61 + 2147493457 = 2147493518
109 + 2147493409 = 2147493518
127 + 2147493391 = 2147493518
229 + 2147493289 = 2147493518
241 + 2147493277 = 2147493518
277 + 2147493241 = 2147493518
349 + 2147493169 = 2147493518
409 + 2147493109 = 2147493518

Showing the first eight; more decompositions exist.
