Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1040228, here are decompositions:

37 + 1040191 = 1040228
61 + 1040167 = 1040228
67 + 1040161 = 1040228
109 + 1040119 = 1040228
127 + 1040101 = 1040228
139 + 1040089 = 1040228
157 + 1040071 = 1040228
199 + 1040029 = 1040228

Showing the first eight; more decompositions exist.
