Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491402, here are decompositions:

41 + 2147491361 = 2147491402
53 + 2147491349 = 2147491402
59 + 2147491343 = 2147491402
83 + 2147491319 = 2147491402
179 + 2147491223 = 2147491402
263 + 2147491139 = 2147491402
311 + 2147491091 = 2147491402
359 + 2147491043 = 2147491402

Showing the first eight; more decompositions exist.
