Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749584, here are decompositions:

5 + 8749579 = 8749584
13 + 8749571 = 8749584
127 + 8749457 = 8749584
163 + 8749421 = 8749584
167 + 8749417 = 8749584
227 + 8749357 = 8749584
241 + 8749343 = 8749584
421 + 8749163 = 8749584

Showing the first eight; more decompositions exist.
