Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188678, here are decompositions:

151 + 188527 = 188678
241 + 188437 = 188678
271 + 188407 = 188678
277 + 188401 = 188678
367 + 188311 = 188678
379 + 188299 = 188678
397 + 188281 = 188678
499 + 188179 = 188678

Showing the first eight; more decompositions exist.
