Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85386, here are decompositions:

5 + 85381 = 85386
17 + 85369 = 85386
23 + 85363 = 85386
53 + 85333 = 85386
73 + 85313 = 85386
83 + 85303 = 85386
89 + 85297 = 85386
127 + 85259 = 85386

Showing the first eight; more decompositions exist.
