Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009690, here are decompositions:

41 + 1009649 = 1009690
47 + 1009643 = 1009690
53 + 1009637 = 1009690
89 + 1009601 = 1009690
131 + 1009559 = 1009690
191 + 1009499 = 1009690
233 + 1009457 = 1009690
251 + 1009439 = 1009690

Showing the first eight; more decompositions exist.
