Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85516, here are decompositions:

3 + 85513 = 85516
29 + 85487 = 85516
47 + 85469 = 85516
89 + 85427 = 85516
257 + 85259 = 85516
269 + 85247 = 85516
293 + 85223 = 85516
317 + 85199 = 85516

Showing the first eight; more decompositions exist.
