Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179438, here are decompositions:

31 + 179407 = 179438
151 + 179287 = 179438
157 + 179281 = 179438
229 + 179209 = 179438
271 + 179167 = 179438
277 + 179161 = 179438
331 + 179107 = 179438
349 + 179089 = 179438

Showing the first eight; more decompositions exist.
