Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1017830, here are decompositions:

3 + 1017827 = 1017830
13 + 1017817 = 1017830
31 + 1017799 = 1017830
43 + 1017787 = 1017830
109 + 1017721 = 1017830
127 + 1017703 = 1017830
157 + 1017673 = 1017830
181 + 1017649 = 1017830

Showing the first eight; more decompositions exist.
