Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022788, here are decompositions:

59 + 1022729 = 1022788
149 + 1022639 = 1022788
197 + 1022591 = 1022788
257 + 1022531 = 1022788
269 + 1022519 = 1022788
281 + 1022507 = 1022788
359 + 1022429 = 1022788
401 + 1022387 = 1022788

Showing the first eight; more decompositions exist.
