Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622680, here are decompositions:

103 + 8622577 = 8622680
151 + 8622529 = 8622680
181 + 8622499 = 8622680
193 + 8622487 = 8622680
211 + 8622469 = 8622680
307 + 8622373 = 8622680
337 + 8622343 = 8622680
349 + 8622331 = 8622680

Showing the first eight; more decompositions exist.
