Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491418, here are decompositions:

157 + 2147491261 = 2147491418
181 + 2147491237 = 2147491418
199 + 2147491219 = 2147491418
307 + 2147491111 = 2147491418
337 + 2147491081 = 2147491418
349 + 2147491069 = 2147491418
421 + 2147490997 = 2147491418
547 + 2147490871 = 2147491418

Showing the first eight; more decompositions exist.
