Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85444, here are decompositions:

5 + 85439 = 85444
17 + 85427 = 85444
83 + 85361 = 85444
113 + 85331 = 85444
131 + 85313 = 85444
197 + 85247 = 85444
251 + 85193 = 85444
311 + 85133 = 85444

Showing the first eight; more decompositions exist.
