Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187268, here are decompositions:

31 + 187237 = 187268
79 + 187189 = 187268
97 + 187171 = 187268
127 + 187141 = 187268
139 + 187129 = 187268
157 + 187111 = 187268
199 + 187069 = 187268
241 + 187027 = 187268

Showing the first eight; more decompositions exist.
