Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008720, here are decompositions:

19 + 1008701 = 1008720
61 + 1008659 = 1008720
103 + 1008617 = 1008720
107 + 1008613 = 1008720
109 + 1008611 = 1008720
113 + 1008607 = 1008720
131 + 1008589 = 1008720
149 + 1008571 = 1008720

Showing the first eight; more decompositions exist.
