Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008380, here are decompositions:

7 + 1008373 = 1008380
151 + 1008229 = 1008380
157 + 1008223 = 1008380
181 + 1008199 = 1008380
193 + 1008187 = 1008380
199 + 1008181 = 1008380
223 + 1008157 = 1008380
337 + 1008043 = 1008380

Showing the first eight; more decompositions exist.
