Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008188, here are decompositions:

7 + 1008181 = 1008188
31 + 1008157 = 1008188
151 + 1008037 = 1008188
157 + 1008031 = 1008188
211 + 1007977 = 1008188
229 + 1007959 = 1008188
331 + 1007857 = 1008188
421 + 1007767 = 1008188

Showing the first eight; more decompositions exist.
