Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629458, here are decompositions:

11 + 8629447 = 8629458
17 + 8629441 = 8629458
29 + 8629429 = 8629458
109 + 8629349 = 8629458
179 + 8629279 = 8629458
317 + 8629141 = 8629458
349 + 8629109 = 8629458
379 + 8629079 = 8629458

Showing the first eight; more decompositions exist.
