Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020872, here are decompositions:

19 + 1020853 = 1020872
31 + 1020841 = 1020872
163 + 1020709 = 1020872
241 + 1020631 = 1020872
283 + 1020589 = 1020872
331 + 1020541 = 1020872
421 + 1020451 = 1020872
571 + 1020301 = 1020872

Showing the first eight; more decompositions exist.
