Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020738, here are decompositions:

29 + 1020709 = 1020738
31 + 1020707 = 1020738
71 + 1020667 = 1020738
107 + 1020631 = 1020738
139 + 1020599 = 1020738
149 + 1020589 = 1020738
181 + 1020557 = 1020738
197 + 1020541 = 1020738

Showing the first eight; more decompositions exist.
