Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85380, here are decompositions:

11 + 85369 = 85380
17 + 85363 = 85380
19 + 85361 = 85380
47 + 85333 = 85380
67 + 85313 = 85380
83 + 85297 = 85380
137 + 85243 = 85380
151 + 85229 = 85380

Showing the first eight; more decompositions exist.
