Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018340, here are decompositions:

3 + 1018337 = 1018340
31 + 1018309 = 1018340
139 + 1018201 = 1018340
163 + 1018177 = 1018340
283 + 1018057 = 1018340
523 + 1017817 = 1018340
541 + 1017799 = 1018340
619 + 1017721 = 1018340

Showing the first eight; more decompositions exist.
