Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179558, here are decompositions:

31 + 179527 = 179558
61 + 179497 = 179558
79 + 179479 = 179558
97 + 179461 = 179558
151 + 179407 = 179558
241 + 179317 = 179558
271 + 179287 = 179558
277 + 179281 = 179558

Showing the first eight; more decompositions exist.
