Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022342, here are decompositions:

151 + 1022191 = 1022342
163 + 1022179 = 1022342
229 + 1022113 = 1022342
271 + 1022071 = 1022342
283 + 1022059 = 1022342
331 + 1022011 = 1022342
379 + 1021963 = 1022342
463 + 1021879 = 1022342

Showing the first eight; more decompositions exist.
