Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637520, here are decompositions:

11 + 8637509 = 8637520
29 + 8637491 = 8637520
53 + 8637467 = 8637520
71 + 8637449 = 8637520
179 + 8637341 = 8637520
197 + 8637323 = 8637520
257 + 8637263 = 8637520
263 + 8637257 = 8637520

Showing the first eight; more decompositions exist.
