Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490782, here are decompositions:

13 + 2147490769 = 2147490782
43 + 2147490739 = 2147490782
193 + 2147490589 = 2147490782
331 + 2147490451 = 2147490782
421 + 2147490361 = 2147490782
439 + 2147490343 = 2147490782
499 + 2147490283 = 2147490782
673 + 2147490109 = 2147490782

Showing the first eight; more decompositions exist.
