Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188636, here are decompositions:

3 + 188633 = 188636
73 + 188563 = 188636
103 + 188533 = 188636
109 + 188527 = 188636
163 + 188473 = 188636
193 + 188443 = 188636
199 + 188437 = 188636
229 + 188407 = 188636

Showing the first eight; more decompositions exist.
