Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77180, here are decompositions:

13 + 77167 = 77180
43 + 77137 = 77180
79 + 77101 = 77180
139 + 77041 = 77180
151 + 77029 = 77180
157 + 77023 = 77180
163 + 77017 = 77180
307 + 76873 = 77180

Showing the first eight; more decompositions exist.
