Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732528, here are decompositions:

67 + 8732461 = 8732528
97 + 8732431 = 8732528
157 + 8732371 = 8732528
229 + 8732299 = 8732528
271 + 8732257 = 8732528
331 + 8732197 = 8732528
457 + 8732071 = 8732528
499 + 8732029 = 8732528

Showing the first eight; more decompositions exist.
