Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749494, here are decompositions:

37 + 8749457 = 8749494
43 + 8749451 = 8749494
71 + 8749423 = 8749494
73 + 8749421 = 8749494
137 + 8749357 = 8749494
151 + 8749343 = 8749494
157 + 8749337 = 8749494
163 + 8749331 = 8749494

Showing the first eight; more decompositions exist.
