Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022806, here are decompositions:

167 + 1022639 = 1022806
173 + 1022633 = 1022806
233 + 1022573 = 1022806
293 + 1022513 = 1022806
419 + 1022387 = 1022806
503 + 1022303 = 1022806
557 + 1022249 = 1022806
563 + 1022243 = 1022806

Showing the first eight; more decompositions exist.
