Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1017840, here are decompositions:

13 + 1017827 = 1017840
23 + 1017817 = 1017840
41 + 1017799 = 1017840
53 + 1017787 = 1017840
59 + 1017781 = 1017840
127 + 1017713 = 1017840
137 + 1017703 = 1017840
157 + 1017683 = 1017840

Showing the first eight; more decompositions exist.
