Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85390, here are decompositions:

29 + 85361 = 85390
59 + 85331 = 85390
131 + 85259 = 85390
167 + 85223 = 85390
191 + 85199 = 85390
197 + 85193 = 85390
257 + 85133 = 85390
269 + 85121 = 85390

Showing the first eight; more decompositions exist.
