Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188628, here are decompositions:

7 + 188621 = 188628
19 + 188609 = 188628
101 + 188527 = 188628
109 + 188519 = 188628
137 + 188491 = 188628
191 + 188437 = 188628
197 + 188431 = 188628
211 + 188417 = 188628

Showing the first eight; more decompositions exist.
