Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77140, here are decompositions:

3 + 77137 = 77140
47 + 77093 = 77140
59 + 77081 = 77140
71 + 77069 = 77140
137 + 77003 = 77140
149 + 76991 = 77140
179 + 76961 = 77140
191 + 76949 = 77140

Showing the first eight; more decompositions exist.
