Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77108, here are decompositions:

7 + 77101 = 77108
61 + 77047 = 77108
67 + 77041 = 77108
79 + 77029 = 77108
271 + 76837 = 77108
277 + 76831 = 77108
307 + 76801 = 77108
331 + 76777 = 77108

Showing the first eight; more decompositions exist.
