Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156018, here are decompositions:

7 + 156011 = 156018
11 + 156007 = 156018
97 + 155921 = 156018
127 + 155891 = 156018
131 + 155887 = 156018
157 + 155861 = 156018
167 + 155851 = 156018
197 + 155821 = 156018

Showing the first eight; more decompositions exist.
