Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478822, here are decompositions:

11 + 478811 = 478822
53 + 478769 = 478822
59 + 478763 = 478822
83 + 478739 = 478822
191 + 478631 = 478822
233 + 478589 = 478822
251 + 478571 = 478822
389 + 478433 = 478822

Showing the first eight; more decompositions exist.
