Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018358, here are decompositions:

67 + 1018291 = 1018358
151 + 1018207 = 1018358
157 + 1018201 = 1018358
181 + 1018177 = 1018358
337 + 1018021 = 1018358
499 + 1017859 = 1018358
541 + 1017817 = 1018358
571 + 1017787 = 1018358

Showing the first eight; more decompositions exist.
