Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749522, here are decompositions:

53 + 8749469 = 8749522
71 + 8749451 = 8749522
83 + 8749439 = 8749522
101 + 8749421 = 8749522
179 + 8749343 = 8749522
191 + 8749331 = 8749522
293 + 8749229 = 8749522
359 + 8749163 = 8749522

Showing the first eight; more decompositions exist.
