Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178768, here are decompositions:

11 + 178757 = 178768
71 + 178697 = 178768
167 + 178601 = 178768
197 + 178571 = 178768
281 + 178487 = 178768
419 + 178349 = 178768
461 + 178307 = 178768
467 + 178301 = 178768

Showing the first eight; more decompositions exist.
