Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047690, here are decompositions:

19 + 1047671 = 1047690
23 + 1047667 = 1047690
37 + 1047653 = 1047690
41 + 1047649 = 1047690
43 + 1047647 = 1047690
101 + 1047589 = 1047690
103 + 1047587 = 1047690
131 + 1047559 = 1047690

Showing the first eight; more decompositions exist.
