Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147485538, here are decompositions:

127 + 2147485411 = 2147485538
157 + 2147485381 = 2147485538
181 + 2147485357 = 2147485538
229 + 2147485309 = 2147485538
271 + 2147485267 = 2147485538
277 + 2147485261 = 2147485538
337 + 2147485201 = 2147485538
349 + 2147485189 = 2147485538

Showing the first eight; more decompositions exist.
