Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622630, here are decompositions:

19 + 8622611 = 8622630
53 + 8622577 = 8622630
67 + 8622563 = 8622630
101 + 8622529 = 8622630
109 + 8622521 = 8622630
131 + 8622499 = 8622630
139 + 8622491 = 8622630
157 + 8622473 = 8622630

Showing the first eight; more decompositions exist.
