Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749790, here are decompositions:

3 + 8749787 = 8749790
19 + 8749771 = 8749790
37 + 8749753 = 8749790
139 + 8749651 = 8749790
163 + 8749627 = 8749790
211 + 8749579 = 8749790
241 + 8749549 = 8749790
367 + 8749423 = 8749790

Showing the first eight; more decompositions exist.
