Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009812, here are decompositions:

5 + 1009807 = 1009812
31 + 1009781 = 1009812
71 + 1009741 = 1009812
163 + 1009649 = 1009812
191 + 1009621 = 1009812
211 + 1009601 = 1009812
239 + 1009573 = 1009812
281 + 1009531 = 1009812

Showing the first eight; more decompositions exist.
