Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1017872, here are decompositions:

13 + 1017859 = 1017872
73 + 1017799 = 1017872
151 + 1017721 = 1017872
199 + 1017673 = 1017872
223 + 1017649 = 1017872
313 + 1017559 = 1017872
433 + 1017439 = 1017872
571 + 1017301 = 1017872

Showing the first eight; more decompositions exist.
