Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85856, here are decompositions:

3 + 85853 = 85856
13 + 85843 = 85856
19 + 85837 = 85856
37 + 85819 = 85856
139 + 85717 = 85856
229 + 85627 = 85856
307 + 85549 = 85856
409 + 85447 = 85856

Showing the first eight; more decompositions exist.
