Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85408, here are decompositions:

47 + 85361 = 85408
149 + 85259 = 85408
179 + 85229 = 85408
317 + 85091 = 85408
347 + 85061 = 85408
359 + 85049 = 85408
431 + 84977 = 85408
461 + 84947 = 85408

Showing the first eight; more decompositions exist.
