Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020686, here are decompositions:

3 + 1020683 = 1020686
19 + 1020667 = 1020686
67 + 1020619 = 1020686
97 + 1020589 = 1020686
103 + 1020583 = 1020686
157 + 1020529 = 1020686
229 + 1020457 = 1020686
307 + 1020379 = 1020686

Showing the first eight; more decompositions exist.
