Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018078, here are decompositions:

59 + 1018019 = 1018078
71 + 1018007 = 1018078
197 + 1017881 = 1018078
227 + 1017851 = 1018078
251 + 1017827 = 1018078
359 + 1017719 = 1018078
431 + 1017647 = 1018078
461 + 1017617 = 1018078

Showing the first eight; more decompositions exist.
