Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188758, here are decompositions:

5 + 188753 = 188758
29 + 188729 = 188758
47 + 188711 = 188758
71 + 188687 = 188758
137 + 188621 = 188758
149 + 188609 = 188758
179 + 188579 = 188758
239 + 188519 = 188758

Showing the first eight; more decompositions exist.
