Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018208, here are decompositions:

7 + 1018201 = 1018208
31 + 1018177 = 1018208
151 + 1018057 = 1018208
211 + 1017997 = 1018208
349 + 1017859 = 1018208
409 + 1017799 = 1018208
421 + 1017787 = 1018208
487 + 1017721 = 1018208

Showing the first eight; more decompositions exist.
