Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621422, here are decompositions:

11 + 8621411 = 8621422
83 + 8621339 = 8621422
113 + 8621309 = 8621422
179 + 8621243 = 8621422
233 + 8621189 = 8621422
239 + 8621183 = 8621422
269 + 8621153 = 8621422
449 + 8620973 = 8621422

Showing the first eight; more decompositions exist.
