Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188644, here are decompositions:

11 + 188633 = 188644
23 + 188621 = 188644
41 + 188603 = 188644
227 + 188417 = 188644
293 + 188351 = 188644
311 + 188333 = 188644
353 + 188291 = 188644
383 + 188261 = 188644

Showing the first eight; more decompositions exist.
