Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 167290, here are decompositions:

23 + 167267 = 167290
29 + 167261 = 167290
41 + 167249 = 167290
113 + 167177 = 167290
131 + 167159 = 167290
173 + 167117 = 167290
191 + 167099 = 167290
239 + 167051 = 167290

Showing the first eight; more decompositions exist.
