Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78040, here are decompositions:

23 + 78017 = 78040
41 + 77999 = 78040
71 + 77969 = 78040
89 + 77951 = 78040
107 + 77933 = 78040
173 + 77867 = 78040
191 + 77849 = 78040
227 + 77813 = 78040

Showing the first eight; more decompositions exist.
