Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621222, here are decompositions:

13 + 8621209 = 8621222
79 + 8621143 = 8621222
139 + 8621083 = 8621222
229 + 8620993 = 8621222
271 + 8620951 = 8621222
349 + 8620873 = 8621222
499 + 8620723 = 8621222
601 + 8620621 = 8621222

Showing the first eight; more decompositions exist.
