Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8634578, here are decompositions:

61 + 8634517 = 8634578
97 + 8634481 = 8634578
109 + 8634469 = 8634578
151 + 8634427 = 8634578
157 + 8634421 = 8634578
181 + 8634397 = 8634578
367 + 8634211 = 8634578
409 + 8634169 = 8634578

Showing the first eight; more decompositions exist.
