Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188456, here are decompositions:

13 + 188443 = 188456
19 + 188437 = 188456
67 + 188389 = 188456
97 + 188359 = 188456
139 + 188317 = 188456
157 + 188299 = 188456
277 + 188179 = 188456
313 + 188143 = 188456

Showing the first eight; more decompositions exist.
