Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85438, here are decompositions:

11 + 85427 = 85438
107 + 85331 = 85438
179 + 85259 = 85438
191 + 85247 = 85438
239 + 85199 = 85438
317 + 85121 = 85438
347 + 85091 = 85438
389 + 85049 = 85438

Showing the first eight; more decompositions exist.
