Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022782, here are decompositions:

53 + 1022729 = 1022782
149 + 1022633 = 1022782
191 + 1022591 = 1022782
251 + 1022531 = 1022782
263 + 1022519 = 1022782
269 + 1022513 = 1022782
281 + 1022501 = 1022782
353 + 1022429 = 1022782

Showing the first eight; more decompositions exist.
