Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020740, here are decompositions:

31 + 1020709 = 1020740
73 + 1020667 = 1020740
109 + 1020631 = 1020740
151 + 1020589 = 1020740
157 + 1020583 = 1020740
199 + 1020541 = 1020740
211 + 1020529 = 1020740
223 + 1020517 = 1020740

Showing the first eight; more decompositions exist.
