Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742798, here are decompositions:

11 + 8742787 = 8742798
19 + 8742779 = 8742798
59 + 8742739 = 8742798
109 + 8742689 = 8742798
227 + 8742571 = 8742798
257 + 8742541 = 8742798
269 + 8742529 = 8742798
349 + 8742449 = 8742798

Showing the first eight; more decompositions exist.
