Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 149154, here are decompositions:

11 + 149143 = 149154
41 + 149113 = 149154
43 + 149111 = 149154
53 + 149101 = 149154
67 + 149087 = 149154
97 + 149057 = 149154
101 + 149053 = 149154
127 + 149027 = 149154

Showing the first eight; more decompositions exist.
