Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641622, here are decompositions:

19 + 8641603 = 8641622
79 + 8641543 = 8641622
103 + 8641519 = 8641622
109 + 8641513 = 8641622
151 + 8641471 = 8641622
193 + 8641429 = 8641622
271 + 8641351 = 8641622
313 + 8641309 = 8641622

Showing the first eight; more decompositions exist.
