Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490692, here are decompositions:

3 + 2147490689 = 2147490692
103 + 2147490589 = 2147490692
163 + 2147490529 = 2147490692
229 + 2147490463 = 2147490692
241 + 2147490451 = 2147490692
331 + 2147490361 = 2147490692
349 + 2147490343 = 2147490692
409 + 2147490283 = 2147490692

Showing the first eight; more decompositions exist.
