Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629572, here are decompositions:

11 + 8629561 = 8629572
89 + 8629483 = 8629572
131 + 8629441 = 8629572
139 + 8629433 = 8629572
163 + 8629409 = 8629572
223 + 8629349 = 8629572
229 + 8629343 = 8629572
239 + 8629333 = 8629572

Showing the first eight; more decompositions exist.
