Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490458, here are decompositions:

7 + 2147490451 = 2147490458
97 + 2147490361 = 2147490458
229 + 2147490229 = 2147490458
241 + 2147490217 = 2147490458
349 + 2147490109 = 2147490458
397 + 2147490061 = 2147490458
541 + 2147489917 = 2147490458
661 + 2147489797 = 2147490458

Showing the first eight; more decompositions exist.
