Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8706520, here are decompositions:

23 + 8706497 = 8706520
41 + 8706479 = 8706520
59 + 8706461 = 8706520
101 + 8706419 = 8706520
107 + 8706413 = 8706520
113 + 8706407 = 8706520
197 + 8706323 = 8706520
233 + 8706287 = 8706520

Showing the first eight; more decompositions exist.
