Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742838, here are decompositions:

17 + 8742821 = 8742838
59 + 8742779 = 8742838
149 + 8742689 = 8742838
389 + 8742449 = 8742838
479 + 8742359 = 8742838
491 + 8742347 = 8742838
521 + 8742317 = 8742838
641 + 8742197 = 8742838

Showing the first eight; more decompositions exist.
