Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009290, here are decompositions:

31 + 1009259 = 1009290
43 + 1009247 = 1009290
47 + 1009243 = 1009290
53 + 1009237 = 1009290
83 + 1009207 = 1009290
89 + 1009201 = 1009290
97 + 1009193 = 1009290
101 + 1009189 = 1009290

Showing the first eight; more decompositions exist.
