Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78118, here are decompositions:

17 + 78101 = 78118
59 + 78059 = 78118
101 + 78017 = 78118
149 + 77969 = 78118
167 + 77951 = 78118
251 + 77867 = 78118
269 + 77849 = 78118
317 + 77801 = 78118

Showing the first eight; more decompositions exist.
