Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028612, here are decompositions:

31 + 1028581 = 1028612
43 + 1028569 = 1028612
103 + 1028509 = 1028612
139 + 1028473 = 1028612
223 + 1028389 = 1028612
283 + 1028329 = 1028612
349 + 1028263 = 1028612
421 + 1028191 = 1028612

Showing the first eight; more decompositions exist.
