Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491284, here are decompositions:

7 + 2147491277 = 2147491284
11 + 2147491273 = 2147491284
23 + 2147491261 = 2147491284
47 + 2147491237 = 2147491284
61 + 2147491223 = 2147491284
67 + 2147491217 = 2147491284
83 + 2147491201 = 2147491284
157 + 2147491127 = 2147491284

Showing the first eight; more decompositions exist.
