Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77144, here are decompositions:

3 + 77141 = 77144
7 + 77137 = 77144
43 + 77101 = 77144
97 + 77047 = 77144
103 + 77041 = 77144
127 + 77017 = 77144
181 + 76963 = 77144
271 + 76873 = 77144

Showing the first eight; more decompositions exist.
