Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002228, here are decompositions:

37 + 1002191 = 1002228
79 + 1002149 = 1002228
107 + 1002121 = 1002228
127 + 1002101 = 1002228
137 + 1002091 = 1002228
151 + 1002077 = 1002228
167 + 1002061 = 1002228
179 + 1002049 = 1002228

Showing the first eight; more decompositions exist.
