Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028742, here are decompositions:

5 + 1028737 = 1028742
59 + 1028683 = 1028742
61 + 1028681 = 1028742
73 + 1028669 = 1028742
79 + 1028663 = 1028742
163 + 1028579 = 1028742
173 + 1028569 = 1028742
181 + 1028561 = 1028742

Showing the first eight; more decompositions exist.
