Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179156, here are decompositions:

13 + 179143 = 179156
37 + 179119 = 179156
67 + 179089 = 179156
73 + 179083 = 179156
127 + 179029 = 179156
223 + 178933 = 179156
283 + 178873 = 179156
337 + 178819 = 179156

Showing the first eight; more decompositions exist.
