Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187338, here are decompositions:

61 + 187277 = 187338
101 + 187237 = 187338
127 + 187211 = 187338
149 + 187189 = 187338
157 + 187181 = 187338
167 + 187171 = 187338
197 + 187141 = 187338
199 + 187139 = 187338

Showing the first eight; more decompositions exist.
