Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629626, here are decompositions:

13 + 8629613 = 8629626
29 + 8629597 = 8629626
43 + 8629583 = 8629626
179 + 8629447 = 8629626
193 + 8629433 = 8629626
197 + 8629429 = 8629626
277 + 8629349 = 8629626
283 + 8629343 = 8629626

Showing the first eight; more decompositions exist.
