Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1017640, here are decompositions:

17 + 1017623 = 1017640
23 + 1017617 = 1017640
89 + 1017551 = 1017640
101 + 1017539 = 1017640
167 + 1017473 = 1017640
191 + 1017449 = 1017640
257 + 1017383 = 1017640
263 + 1017377 = 1017640

Showing the first eight; more decompositions exist.
