Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178368, here are decompositions:

7 + 178361 = 178368
17 + 178351 = 178368
19 + 178349 = 178368
41 + 178327 = 178368
61 + 178307 = 178368
67 + 178301 = 178368
79 + 178289 = 178368
107 + 178261 = 178368

Showing the first eight; more decompositions exist.
