Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8753520, here are decompositions:

7 + 8753513 = 8753520
31 + 8753489 = 8753520
59 + 8753461 = 8753520
71 + 8753449 = 8753520
79 + 8753441 = 8753520
151 + 8753369 = 8753520
227 + 8753293 = 8753520
229 + 8753291 = 8753520

Showing the first eight; more decompositions exist.
