Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147486650, here are decompositions:

137 + 2147486513 = 2147486650
149 + 2147486501 = 2147486650
191 + 2147486459 = 2147486650
227 + 2147486423 = 2147486650
251 + 2147486399 = 2147486650
263 + 2147486387 = 2147486650
311 + 2147486339 = 2147486650
401 + 2147486249 = 2147486650

Showing the first eight; more decompositions exist.
