Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188162, here are decompositions:

3 + 188159 = 188162
19 + 188143 = 188162
151 + 188011 = 188162
199 + 187963 = 188162
211 + 187951 = 188162
241 + 187921 = 188162
463 + 187699 = 188162
523 + 187639 = 188162

Showing the first eight; more decompositions exist.
