Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629446, here are decompositions:

5 + 8629441 = 8629446
13 + 8629433 = 8629446
17 + 8629429 = 8629446
37 + 8629409 = 8629446
97 + 8629349 = 8629446
103 + 8629343 = 8629446
113 + 8629333 = 8629446
149 + 8629297 = 8629446

Showing the first eight; more decompositions exist.
