Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636520, here are decompositions:

7 + 8636513 = 8636520
29 + 8636491 = 8636520
47 + 8636473 = 8636520
71 + 8636449 = 8636520
97 + 8636423 = 8636520
131 + 8636389 = 8636520
173 + 8636347 = 8636520
251 + 8636269 = 8636520

Showing the first eight; more decompositions exist.
