Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642616, here are decompositions:

83 + 8642533 = 8642616
97 + 8642519 = 8642616
107 + 8642509 = 8642616
109 + 8642507 = 8642616
127 + 8642489 = 8642616
149 + 8642467 = 8642616
163 + 8642453 = 8642616
167 + 8642449 = 8642616

Showing the first eight; more decompositions exist.
