Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188458, here are decompositions:

41 + 188417 = 188458
89 + 188369 = 188458
107 + 188351 = 188458
167 + 188291 = 188458
197 + 188261 = 188458
269 + 188189 = 188458
311 + 188147 = 188458
587 + 187871 = 188458

Showing the first eight; more decompositions exist.
