Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008218, here are decompositions:

19 + 1008199 = 1008218
31 + 1008187 = 1008218
37 + 1008181 = 1008218
61 + 1008157 = 1008218
181 + 1008037 = 1008218
241 + 1007977 = 1008218
331 + 1007887 = 1008218
487 + 1007731 = 1008218

Showing the first eight; more decompositions exist.
