Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 151182, here are decompositions:

11 + 151171 = 151182
13 + 151169 = 151182
19 + 151163 = 151182
29 + 151153 = 151182
41 + 151141 = 151182
61 + 151121 = 151182
131 + 151051 = 151182
173 + 151009 = 151182

Showing the first eight; more decompositions exist.
