Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179138, here are decompositions:

19 + 179119 = 179138
31 + 179107 = 179138
97 + 179041 = 179138
109 + 179029 = 179138
151 + 178987 = 179138
199 + 178939 = 179138
229 + 178909 = 179138
241 + 178897 = 179138

Showing the first eight; more decompositions exist.
