Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85558, here are decompositions:

41 + 85517 = 85558
71 + 85487 = 85558
89 + 85469 = 85558
107 + 85451 = 85558
131 + 85427 = 85558
197 + 85361 = 85558
227 + 85331 = 85558
311 + 85247 = 85558

Showing the first eight; more decompositions exist.
