Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139116, here are decompositions:

7 + 139109 = 139116
37 + 139079 = 139116
83 + 139033 = 139116
139 + 138977 = 139116
149 + 138967 = 139116
157 + 138959 = 139116
179 + 138937 = 139116
193 + 138923 = 139116

Showing the first eight; more decompositions exist.
