Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020646, here are decompositions:

47 + 1020599 = 1020646
89 + 1020557 = 1020646
227 + 1020419 = 1020646
233 + 1020413 = 1020646
239 + 1020407 = 1020646
257 + 1020389 = 1020646
293 + 1020353 = 1020646
317 + 1020329 = 1020646

Showing the first eight; more decompositions exist.
