Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022340, here are decompositions:

37 + 1022303 = 1022340
89 + 1022251 = 1022340
97 + 1022243 = 1022340
103 + 1022237 = 1022340
131 + 1022209 = 1022340
139 + 1022201 = 1022340
149 + 1022191 = 1022340
157 + 1022183 = 1022340

Showing the first eight; more decompositions exist.
