Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78102, here are decompositions:

23 + 78079 = 78102
43 + 78059 = 78102
53 + 78049 = 78102
61 + 78041 = 78102
71 + 78031 = 78102
103 + 77999 = 78102
151 + 77951 = 78102
173 + 77929 = 78102

Showing the first eight; more decompositions exist.
