Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009778, here are decompositions:

31 + 1009747 = 1009778
37 + 1009741 = 1009778
109 + 1009669 = 1009778
127 + 1009651 = 1009778
151 + 1009627 = 1009778
157 + 1009621 = 1009778
241 + 1009537 = 1009778
271 + 1009507 = 1009778

Showing the first eight; more decompositions exist.
