Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042666, here are decompositions:

47 + 1042619 = 1042666
59 + 1042607 = 1042666
83 + 1042583 = 1042666
89 + 1042577 = 1042666
137 + 1042529 = 1042666
179 + 1042487 = 1042666
197 + 1042469 = 1042666
227 + 1042439 = 1042666

Showing the first eight; more decompositions exist.
