Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147492878, here are decompositions:

137 + 2147492741 = 2147492878
239 + 2147492639 = 2147492878
257 + 2147492621 = 2147492878
269 + 2147492609 = 2147492878
281 + 2147492597 = 2147492878
389 + 2147492489 = 2147492878
431 + 2147492447 = 2147492878
449 + 2147492429 = 2147492878

Showing the first eight; more decompositions exist.
