Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749482, here are decompositions:

13 + 8749469 = 8749482
31 + 8749451 = 8749482
43 + 8749439 = 8749482
59 + 8749423 = 8749482
61 + 8749421 = 8749482
139 + 8749343 = 8749482
151 + 8749331 = 8749482
173 + 8749309 = 8749482

Showing the first eight; more decompositions exist.
