Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025784, here are decompositions:

17 + 1025767 = 1025784
37 + 1025747 = 1025784
43 + 1025741 = 1025784
131 + 1025653 = 1025784
163 + 1025621 = 1025784
173 + 1025611 = 1025784
223 + 1025561 = 1025784
233 + 1025551 = 1025784

Showing the first eight; more decompositions exist.
