Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022458, here are decompositions:

29 + 1022429 = 1022458
71 + 1022387 = 1022458
167 + 1022291 = 1022458
257 + 1022201 = 1022458
317 + 1022141 = 1022458
659 + 1021799 = 1022458
761 + 1021697 = 1022458
797 + 1021661 = 1022458

Showing the first eight; more decompositions exist.
