Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749474, here are decompositions:

5 + 8749469 = 8749474
17 + 8749457 = 8749474
23 + 8749451 = 8749474
53 + 8749421 = 8749474
131 + 8749343 = 8749474
137 + 8749337 = 8749474
311 + 8749163 = 8749474
347 + 8749127 = 8749474

Showing the first eight; more decompositions exist.
