Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1017800, here are decompositions:

13 + 1017787 = 1017800
19 + 1017781 = 1017800
79 + 1017721 = 1017800
97 + 1017703 = 1017800
127 + 1017673 = 1017800
151 + 1017649 = 1017800
193 + 1017607 = 1017800
241 + 1017559 = 1017800

Showing the first eight; more decompositions exist.
