Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61308, here are decompositions:

11 + 61297 = 61308
17 + 61291 = 61308
47 + 61261 = 61308
97 + 61211 = 61308
139 + 61169 = 61308
157 + 61151 = 61308
167 + 61141 = 61308
179 + 61129 = 61308

Showing the first eight; more decompositions exist.
