Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1012290, here are decompositions:

11 + 1012279 = 1012290
23 + 1012267 = 1012290
29 + 1012261 = 1012290
31 + 1012259 = 1012290
61 + 1012229 = 1012290
73 + 1012217 = 1012290
89 + 1012201 = 1012290
101 + 1012189 = 1012290

Showing the first eight; more decompositions exist.
