Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622690, here are decompositions:

7 + 8622683 = 8622690
79 + 8622611 = 8622690
113 + 8622577 = 8622690
127 + 8622563 = 8622690
179 + 8622511 = 8622690
191 + 8622499 = 8622690
199 + 8622491 = 8622690
227 + 8622463 = 8622690

Showing the first eight; more decompositions exist.
