Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621086, here are decompositions:

3 + 8621083 = 8621086
113 + 8620973 = 8621086
137 + 8620949 = 8621086
239 + 8620847 = 8621086
347 + 8620739 = 8621086
359 + 8620727 = 8621086
449 + 8620637 = 8621086
557 + 8620529 = 8621086

Showing the first eight; more decompositions exist.
