Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020722, here are decompositions:

13 + 1020709 = 1020722
103 + 1020619 = 1020722
139 + 1020583 = 1020722
181 + 1020541 = 1020722
193 + 1020529 = 1020722
271 + 1020451 = 1020722
421 + 1020301 = 1020722
463 + 1020259 = 1020722

Showing the first eight; more decompositions exist.
