Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023660, here are decompositions:

7 + 1023653 = 1023660
17 + 1023643 = 1023660
59 + 1023601 = 1023660
83 + 1023577 = 1023660
89 + 1023571 = 1023660
103 + 1023557 = 1023660
109 + 1023551 = 1023660
139 + 1023521 = 1023660

Showing the first eight; more decompositions exist.
