Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628838, here are decompositions:

47 + 8628791 = 8628838
59 + 8628779 = 8628838
191 + 8628647 = 8628838
359 + 8628479 = 8628838
389 + 8628449 = 8628838
431 + 8628407 = 8628838
461 + 8628377 = 8628838
479 + 8628359 = 8628838

Showing the first eight; more decompositions exist.
