Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85564, here are decompositions:

41 + 85523 = 85564
47 + 85517 = 85564
113 + 85451 = 85564
137 + 85427 = 85564
233 + 85331 = 85564
251 + 85313 = 85564
317 + 85247 = 85564
431 + 85133 = 85564

Showing the first eight; more decompositions exist.
