Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188342, here are decompositions:

19 + 188323 = 188342
31 + 188311 = 188342
43 + 188299 = 188342
61 + 188281 = 188342
163 + 188179 = 188342
199 + 188143 = 188342
313 + 188029 = 188342
331 + 188011 = 188342

Showing the first eight; more decompositions exist.
