Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188268, here are decompositions:

7 + 188261 = 188268
19 + 188249 = 188268
71 + 188197 = 188268
79 + 188189 = 188268
89 + 188179 = 188268
97 + 188171 = 188268
109 + 188159 = 188268
131 + 188137 = 188268

Showing the first eight; more decompositions exist.
