Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489766, here are decompositions:

53 + 2147489713 = 2147489766
67 + 2147489699 = 2147489766
113 + 2147489653 = 2147489766
127 + 2147489639 = 2147489766
179 + 2147489587 = 2147489766
223 + 2147489543 = 2147489766
229 + 2147489537 = 2147489766
263 + 2147489503 = 2147489766

Showing the first eight; more decompositions exist.
