Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022186, here are decompositions:

3 + 1022183 = 1022186
7 + 1022179 = 1022186
19 + 1022167 = 1022186
73 + 1022113 = 1022186
103 + 1022083 = 1022186
127 + 1022059 = 1022186
223 + 1021963 = 1022186
307 + 1021879 = 1022186

Showing the first eight; more decompositions exist.
