Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022072, here are decompositions:

13 + 1022059 = 1022072
19 + 1022053 = 1022072
61 + 1022011 = 1022072
109 + 1021963 = 1022072
193 + 1021879 = 1022072
211 + 1021861 = 1022072
223 + 1021849 = 1022072
241 + 1021831 = 1022072

Showing the first eight; more decompositions exist.
