Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188474, here are decompositions:

31 + 188443 = 188474
37 + 188437 = 188474
43 + 188431 = 188474
67 + 188407 = 188474
73 + 188401 = 188474
151 + 188323 = 188474
157 + 188317 = 188474
163 + 188311 = 188474

Showing the first eight; more decompositions exist.
