Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179290, here are decompositions:

3 + 179287 = 179290
29 + 179261 = 179290
47 + 179243 = 179290
179 + 179111 = 179290
191 + 179099 = 179290
233 + 179057 = 179290
239 + 179051 = 179290
257 + 179033 = 179290

Showing the first eight; more decompositions exist.
