Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188274, here are decompositions:

13 + 188261 = 188274
103 + 188171 = 188274
127 + 188147 = 188274
131 + 188143 = 188274
137 + 188137 = 188274
167 + 188107 = 188274
257 + 188017 = 188274
263 + 188011 = 188274

Showing the first eight; more decompositions exist.
