Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629490, here are decompositions:

7 + 8629483 = 8629490
43 + 8629447 = 8629490
61 + 8629429 = 8629490
157 + 8629333 = 8629490
193 + 8629297 = 8629490
211 + 8629279 = 8629490
277 + 8629213 = 8629490
349 + 8629141 = 8629490

Showing the first eight; more decompositions exist.
