Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748178, here are decompositions:

11 + 8748167 = 8748178
17 + 8748161 = 8748178
41 + 8748137 = 8748178
167 + 8748011 = 8748178
191 + 8747987 = 8748178
251 + 8747927 = 8748178
347 + 8747831 = 8748178
359 + 8747819 = 8748178

Showing the first eight; more decompositions exist.
