Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85388, here are decompositions:

7 + 85381 = 85388
19 + 85369 = 85388
151 + 85237 = 85388
229 + 85159 = 85388
241 + 85147 = 85388
307 + 85081 = 85388
367 + 85021 = 85388
379 + 85009 = 85388

Showing the first eight; more decompositions exist.
