Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490998, here are decompositions:

31 + 2147490967 = 2147490998
127 + 2147490871 = 2147490998
199 + 2147490799 = 2147490998
229 + 2147490769 = 2147490998
271 + 2147490727 = 2147490998
409 + 2147490589 = 2147490998
421 + 2147490577 = 2147490998
547 + 2147490451 = 2147490998

Showing the first eight; more decompositions exist.
