Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020690, here are decompositions:

7 + 1020683 = 1020690
23 + 1020667 = 1020690
59 + 1020631 = 1020690
71 + 1020619 = 1020690
101 + 1020589 = 1020690
107 + 1020583 = 1020690
149 + 1020541 = 1020690
173 + 1020517 = 1020690

Showing the first eight; more decompositions exist.
