Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749528, here are decompositions:

59 + 8749469 = 8749528
71 + 8749457 = 8749528
89 + 8749439 = 8749528
107 + 8749421 = 8749528
191 + 8749337 = 8749528
197 + 8749331 = 8749528
401 + 8749127 = 8749528
479 + 8749049 = 8749528

Showing the first eight; more decompositions exist.
