Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78018, here are decompositions:

11 + 78007 = 78018
19 + 77999 = 78018
41 + 77977 = 78018
67 + 77951 = 78018
89 + 77929 = 78018
151 + 77867 = 78018
179 + 77839 = 78018
257 + 77761 = 78018

Showing the first eight; more decompositions exist.
