Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188540, here are decompositions:

7 + 188533 = 188540
13 + 188527 = 188540
67 + 188473 = 188540
97 + 188443 = 188540
103 + 188437 = 188540
109 + 188431 = 188540
139 + 188401 = 188540
151 + 188389 = 188540

Showing the first eight; more decompositions exist.
