Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009808, here are decompositions:

61 + 1009747 = 1009808
67 + 1009741 = 1009808
139 + 1009669 = 1009808
157 + 1009651 = 1009808
181 + 1009627 = 1009808
199 + 1009609 = 1009808
271 + 1009537 = 1009808
277 + 1009531 = 1009808

Showing the first eight; more decompositions exist.
