Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188354, here are decompositions:

3 + 188351 = 188354
31 + 188323 = 188354
37 + 188317 = 188354
43 + 188311 = 188354
73 + 188281 = 188354
157 + 188197 = 188354
211 + 188143 = 188354
337 + 188017 = 188354

Showing the first eight; more decompositions exist.
