Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77380, here are decompositions:

3 + 77377 = 77380
11 + 77369 = 77380
29 + 77351 = 77380
41 + 77339 = 77380
89 + 77291 = 77380
101 + 77279 = 77380
113 + 77267 = 77380
131 + 77249 = 77380

Showing the first eight; more decompositions exist.
