Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188684, here are decompositions:

3 + 188681 = 188684
7 + 188677 = 188684
31 + 188653 = 188684
151 + 188533 = 188684
157 + 188527 = 188684
193 + 188491 = 188684
211 + 188473 = 188684
241 + 188443 = 188684

Showing the first eight; more decompositions exist.
