Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188308, here are decompositions:

5 + 188303 = 188308
17 + 188291 = 188308
47 + 188261 = 188308
59 + 188249 = 188308
137 + 188171 = 188308
149 + 188159 = 188308
401 + 187907 = 188308
431 + 187877 = 188308

Showing the first eight; more decompositions exist.
