Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020860, here are decompositions:

7 + 1020853 = 1020860
13 + 1020847 = 1020860
19 + 1020841 = 1020860
37 + 1020823 = 1020860
103 + 1020757 = 1020860
109 + 1020751 = 1020860
151 + 1020709 = 1020860
193 + 1020667 = 1020860

Showing the first eight; more decompositions exist.
