Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8746578, here are decompositions:

59 + 8746519 = 8746578
109 + 8746469 = 8746578
131 + 8746447 = 8746578
151 + 8746427 = 8746578
179 + 8746399 = 8746578
199 + 8746379 = 8746578
227 + 8746351 = 8746578
277 + 8746301 = 8746578

Showing the first eight; more decompositions exist.
