Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8665622, here are decompositions:

3 + 8665619 = 8665622
19 + 8665603 = 8665622
61 + 8665561 = 8665622
79 + 8665543 = 8665622
151 + 8665471 = 8665622
181 + 8665441 = 8665622
193 + 8665429 = 8665622
421 + 8665201 = 8665622

Showing the first eight; more decompositions exist.
