Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86378, here are decompositions:

7 + 86371 = 86378
37 + 86341 = 86378
67 + 86311 = 86378
109 + 86269 = 86378
139 + 86239 = 86378
181 + 86197 = 86378
199 + 86179 = 86378
241 + 86137 = 86378

Showing the first eight; more decompositions exist.
