Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8632520, here are decompositions:

7 + 8632513 = 8632520
31 + 8632489 = 8632520
67 + 8632453 = 8632520
97 + 8632423 = 8632520
109 + 8632411 = 8632520
139 + 8632381 = 8632520
157 + 8632363 = 8632520
163 + 8632357 = 8632520

Showing the first eight; more decompositions exist.
