Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61278, here are decompositions:

17 + 61261 = 61278
47 + 61231 = 61278
67 + 61211 = 61278
109 + 61169 = 61278
127 + 61151 = 61278
137 + 61141 = 61278
149 + 61129 = 61278
157 + 61121 = 61278

Showing the first eight; more decompositions exist.
