Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147492390, here are decompositions:

3 + 2147492387 = 2147492390
19 + 2147492371 = 2147492390
37 + 2147492353 = 2147492390
61 + 2147492329 = 2147492390
73 + 2147492317 = 2147492390
151 + 2147492239 = 2147492390
229 + 2147492161 = 2147492390
367 + 2147492023 = 2147492390

Showing the first eight; more decompositions exist.
