Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022230, here are decompositions:

29 + 1022201 = 1022230
47 + 1022183 = 1022230
89 + 1022141 = 1022230
101 + 1022129 = 1022230
107 + 1022123 = 1022230
197 + 1022033 = 1022230
257 + 1021973 = 1022230
269 + 1021961 = 1022230

Showing the first eight; more decompositions exist.
