Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622938, here are decompositions:

61 + 8622877 = 8622938
67 + 8622871 = 8622938
97 + 8622841 = 8622938
127 + 8622811 = 8622938
157 + 8622781 = 8622938
409 + 8622529 = 8622938
439 + 8622499 = 8622938
547 + 8622391 = 8622938

Showing the first eight; more decompositions exist.
