Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188738, here are decompositions:

19 + 188719 = 188738
31 + 188707 = 188738
37 + 188701 = 188738
61 + 188677 = 188738
211 + 188527 = 188738
307 + 188431 = 188738
331 + 188407 = 188738
337 + 188401 = 188738

Showing the first eight; more decompositions exist.
