Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020672, here are decompositions:

5 + 1020667 = 1020672
41 + 1020631 = 1020672
53 + 1020619 = 1020672
73 + 1020599 = 1020672
83 + 1020589 = 1020672
89 + 1020583 = 1020672
131 + 1020541 = 1020672
181 + 1020491 = 1020672

Showing the first eight; more decompositions exist.
