Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019726, here are decompositions:

3 + 1019723 = 1019726
13 + 1019713 = 1019726
79 + 1019647 = 1019726
109 + 1019617 = 1019726
163 + 1019563 = 1019726
193 + 1019533 = 1019726
223 + 1019503 = 1019726
277 + 1019449 = 1019726

Showing the first eight; more decompositions exist.
