Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018268, here are decompositions:

61 + 1018207 = 1018268
67 + 1018201 = 1018268
211 + 1018057 = 1018268
271 + 1017997 = 1018268
379 + 1017889 = 1018268
409 + 1017859 = 1018268
421 + 1017847 = 1018268
487 + 1017781 = 1018268

Showing the first eight; more decompositions exist.
