Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85786, here are decompositions:

5 + 85781 = 85786
53 + 85733 = 85786
83 + 85703 = 85786
167 + 85619 = 85786
179 + 85607 = 85786
263 + 85523 = 85786
269 + 85517 = 85786
317 + 85469 = 85786

Showing the first eight; more decompositions exist.
