Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188318, here are decompositions:

7 + 188311 = 188318
19 + 188299 = 188318
37 + 188281 = 188318
139 + 188179 = 188318
181 + 188137 = 188318
211 + 188107 = 188318
307 + 188011 = 188318
331 + 187987 = 188318

Showing the first eight; more decompositions exist.
