Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179518, here are decompositions:

47 + 179471 = 179518
89 + 179429 = 179518
107 + 179411 = 179518
137 + 179381 = 179518
149 + 179369 = 179518
167 + 179351 = 179518
191 + 179327 = 179518
197 + 179321 = 179518

Showing the first eight; more decompositions exist.
