Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749658, here are decompositions:

7 + 8749651 = 8749658
31 + 8749627 = 8749658
79 + 8749579 = 8749658
109 + 8749549 = 8749658
241 + 8749417 = 8749658
349 + 8749309 = 8749658
439 + 8749219 = 8749658
571 + 8749087 = 8749658

Showing the first eight; more decompositions exist.
