Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77130, here are decompositions:

29 + 77101 = 77130
37 + 77093 = 77130
61 + 77069 = 77130
83 + 77047 = 77130
89 + 77041 = 77130
101 + 77029 = 77130
107 + 77023 = 77130
113 + 77017 = 77130

Showing the first eight; more decompositions exist.
