Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622818, here are decompositions:

7 + 8622811 = 8622818
37 + 8622781 = 8622818
97 + 8622721 = 8622818
241 + 8622577 = 8622818
307 + 8622511 = 8622818
331 + 8622487 = 8622818
349 + 8622469 = 8622818
397 + 8622421 = 8622818

Showing the first eight; more decompositions exist.
