Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629520, here are decompositions:

13 + 8629507 = 8629520
37 + 8629483 = 8629520
73 + 8629447 = 8629520
79 + 8629441 = 8629520
223 + 8629297 = 8629520
241 + 8629279 = 8629520
307 + 8629213 = 8629520
349 + 8629171 = 8629520

Showing the first eight; more decompositions exist.
