Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621146, here are decompositions:

3 + 8621143 = 8621146
59 + 8621087 = 8621146
137 + 8621009 = 8621146
173 + 8620973 = 8621146
197 + 8620949 = 8621146
389 + 8620757 = 8621146
419 + 8620727 = 8621146
509 + 8620637 = 8621146

Showing the first eight; more decompositions exist.
