Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188732, here are decompositions:

3 + 188729 = 188732
13 + 188719 = 188732
31 + 188701 = 188732
79 + 188653 = 188732
199 + 188533 = 188732
241 + 188491 = 188732
331 + 188401 = 188732
373 + 188359 = 188732

Showing the first eight; more decompositions exist.
