Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491246, here are decompositions:

23 + 2147491223 = 2147491246
29 + 2147491217 = 2147491246
53 + 2147491193 = 2147491246
107 + 2147491139 = 2147491246
179 + 2147491067 = 2147491246
227 + 2147491019 = 2147491246
239 + 2147491007 = 2147491246
293 + 2147490953 = 2147491246

Showing the first eight; more decompositions exist.
