Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179390, here are decompositions:

7 + 179383 = 179390
73 + 179317 = 179390
103 + 179287 = 179390
109 + 179281 = 179390
157 + 179233 = 179390
181 + 179209 = 179390
223 + 179167 = 179390
229 + 179161 = 179390

Showing the first eight; more decompositions exist.
