Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749730, here are decompositions:

61 + 8749669 = 8749730
79 + 8749651 = 8749730
103 + 8749627 = 8749730
127 + 8749603 = 8749730
151 + 8749579 = 8749730
181 + 8749549 = 8749730
307 + 8749423 = 8749730
313 + 8749417 = 8749730

Showing the first eight; more decompositions exist.
