Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629786, here are decompositions:

23 + 8629763 = 8629786
47 + 8629739 = 8629786
107 + 8629679 = 8629786
149 + 8629637 = 8629786
173 + 8629613 = 8629786
353 + 8629433 = 8629786
443 + 8629343 = 8629786
587 + 8629199 = 8629786

Showing the first eight; more decompositions exist.
