Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749500, here are decompositions:

31 + 8749469 = 8749500
43 + 8749457 = 8749500
61 + 8749439 = 8749500
79 + 8749421 = 8749500
83 + 8749417 = 8749500
157 + 8749343 = 8749500
163 + 8749337 = 8749500
191 + 8749309 = 8749500

Showing the first eight; more decompositions exist.
