Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188626, here are decompositions:

5 + 188621 = 188626
17 + 188609 = 188626
23 + 188603 = 188626
47 + 188579 = 188626
107 + 188519 = 188626
167 + 188459 = 188626
257 + 188369 = 188626
293 + 188333 = 188626

Showing the first eight; more decompositions exist.
