Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1061660, here are decompositions:

13 + 1061647 = 1061660
31 + 1061629 = 1061660
37 + 1061623 = 1061660
43 + 1061617 = 1061660
151 + 1061509 = 1061660
283 + 1061377 = 1061660
307 + 1061353 = 1061660
337 + 1061323 = 1061660

Showing the first eight; more decompositions exist.
