Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187274, here are decompositions:

37 + 187237 = 187274
97 + 187177 = 187274
103 + 187171 = 187274
151 + 187123 = 187274
163 + 187111 = 187274
193 + 187081 = 187274
271 + 187003 = 187274
397 + 186877 = 187274

Showing the first eight; more decompositions exist.
