Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009786, here are decompositions:

5 + 1009781 = 1009786
59 + 1009727 = 1009786
137 + 1009649 = 1009786
149 + 1009637 = 1009786
227 + 1009559 = 1009786
347 + 1009439 = 1009786
353 + 1009433 = 1009786
443 + 1009343 = 1009786

Showing the first eight; more decompositions exist.
