Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43178, here are decompositions:

19 + 43159 = 43178
61 + 43117 = 43178
127 + 43051 = 43178
199 + 42979 = 43178
211 + 42967 = 43178
241 + 42937 = 43178
277 + 42901 = 43178
337 + 42841 = 43178

Showing the first eight; more decompositions exist.
