Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188668, here are decompositions:

47 + 188621 = 188668
59 + 188609 = 188668
89 + 188579 = 188668
149 + 188519 = 188668
251 + 188417 = 188668
317 + 188351 = 188668
419 + 188249 = 188668
479 + 188189 = 188668

Showing the first eight; more decompositions exist.
