Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8761528, here are decompositions:

11 + 8761517 = 8761528
59 + 8761469 = 8761528
71 + 8761457 = 8761528
89 + 8761439 = 8761528
239 + 8761289 = 8761528
359 + 8761169 = 8761528
389 + 8761139 = 8761528
449 + 8761079 = 8761528

Showing the first eight; more decompositions exist.
