Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1054640, here are decompositions:

19 + 1054621 = 1054640
31 + 1054609 = 1054640
43 + 1054597 = 1054640
109 + 1054531 = 1054640
157 + 1054483 = 1054640
163 + 1054477 = 1054640
199 + 1054441 = 1054640
211 + 1054429 = 1054640

Showing the first eight; more decompositions exist.
