Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187154, here are decompositions:

13 + 187141 = 187154
31 + 187123 = 187154
43 + 187111 = 187154
73 + 187081 = 187154
127 + 187027 = 187154
151 + 187003 = 187154
271 + 186883 = 187154
277 + 186877 = 187154

Showing the first eight; more decompositions exist.
