Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 149290, here are decompositions:

3 + 149287 = 149290
41 + 149249 = 149290
107 + 149183 = 149290
131 + 149159 = 149290
137 + 149153 = 149290
179 + 149111 = 149290
191 + 149099 = 149290
233 + 149057 = 149290

Showing the first eight; more decompositions exist.
