Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045686, here are decompositions:

7 + 1045679 = 1045686
23 + 1045663 = 1045686
43 + 1045643 = 1045686
53 + 1045633 = 1045686
79 + 1045607 = 1045686
113 + 1045573 = 1045686
127 + 1045559 = 1045686
137 + 1045549 = 1045686

Showing the first eight; more decompositions exist.
