Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022686, here are decompositions:

3 + 1022683 = 1022686
47 + 1022639 = 1022686
53 + 1022633 = 1022686
113 + 1022573 = 1022686
167 + 1022519 = 1022686
173 + 1022513 = 1022686
179 + 1022507 = 1022686
257 + 1022429 = 1022686

Showing the first eight; more decompositions exist.
