Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022654, here are decompositions:

43 + 1022611 = 1022654
151 + 1022503 = 1022654
163 + 1022491 = 1022654
211 + 1022443 = 1022654
271 + 1022383 = 1022654
277 + 1022377 = 1022654
313 + 1022341 = 1022654
463 + 1022191 = 1022654

Showing the first eight; more decompositions exist.
