Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622386, here are decompositions:

7 + 8622379 = 8622386
13 + 8622373 = 8622386
43 + 8622343 = 8622386
79 + 8622307 = 8622386
163 + 8622223 = 8622386
379 + 8622007 = 8622386
397 + 8621989 = 8622386
439 + 8621947 = 8622386

Showing the first eight; more decompositions exist.
