Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188528, here are decompositions:

37 + 188491 = 188528
97 + 188431 = 188528
127 + 188401 = 188528
139 + 188389 = 188528
211 + 188317 = 188528
229 + 188299 = 188528
331 + 188197 = 188528
349 + 188179 = 188528

Showing the first eight; more decompositions exist.
