Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749506, here are decompositions:

37 + 8749469 = 8749506
67 + 8749439 = 8749506
83 + 8749423 = 8749506
89 + 8749417 = 8749506
149 + 8749357 = 8749506
163 + 8749343 = 8749506
197 + 8749309 = 8749506
263 + 8749243 = 8749506

Showing the first eight; more decompositions exist.
