Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155154, here are decompositions:

17 + 155137 = 155154
67 + 155087 = 155154
71 + 155083 = 155154
73 + 155081 = 155154
107 + 155047 = 155154
127 + 155027 = 155154
137 + 155017 = 155154
151 + 155003 = 155154

Showing the first eight; more decompositions exist.
