Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622236, here are decompositions:

13 + 8622223 = 8622236
109 + 8622127 = 8622236
229 + 8622007 = 8622236
277 + 8621959 = 8622236
367 + 8621869 = 8622236
373 + 8621863 = 8622236
379 + 8621857 = 8622236
409 + 8621827 = 8622236

Showing the first eight; more decompositions exist.
