Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742822, here are decompositions:

5 + 8742817 = 8742822
43 + 8742779 = 8742822
83 + 8742739 = 8742822
149 + 8742673 = 8742822
199 + 8742623 = 8742822
251 + 8742571 = 8742822
271 + 8742551 = 8742822
281 + 8742541 = 8742822

Showing the first eight; more decompositions exist.
