Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178460, here are decompositions:

13 + 178447 = 178460
19 + 178441 = 178460
43 + 178417 = 178460
67 + 178393 = 178460
109 + 178351 = 178460
127 + 178333 = 178460
199 + 178261 = 178460
211 + 178249 = 178460

Showing the first eight; more decompositions exist.
