Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018168, here are decompositions:

59 + 1018109 = 1018168
71 + 1018097 = 1018168
149 + 1018019 = 1018168
311 + 1017857 = 1018168
317 + 1017851 = 1018168
419 + 1017749 = 1018168
449 + 1017719 = 1018168
521 + 1017647 = 1018168

Showing the first eight; more decompositions exist.
