Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77122, here are decompositions:

29 + 77093 = 77122
41 + 77081 = 77122
53 + 77069 = 77122
131 + 76991 = 77122
173 + 76949 = 77122
179 + 76943 = 77122
239 + 76883 = 77122
251 + 76871 = 77122

Showing the first eight; more decompositions exist.
