Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491202, here are decompositions:

79 + 2147491123 = 2147491202
229 + 2147490973 = 2147491202
331 + 2147490871 = 2147491202
433 + 2147490769 = 2147491202
463 + 2147490739 = 2147491202
613 + 2147490589 = 2147491202
673 + 2147490529 = 2147491202
739 + 2147490463 = 2147491202

Showing the first eight; more decompositions exist.
