Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178374, here are decompositions:

13 + 178361 = 178374
23 + 178351 = 178374
41 + 178333 = 178374
47 + 178327 = 178374
67 + 178307 = 178374
73 + 178301 = 178374
113 + 178261 = 178374
127 + 178247 = 178374

Showing the first eight; more decompositions exist.
