Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85838, here are decompositions:

7 + 85831 = 85838
19 + 85819 = 85838
127 + 85711 = 85838
199 + 85639 = 85838
211 + 85627 = 85838
241 + 85597 = 85838
307 + 85531 = 85838
409 + 85429 = 85838

Showing the first eight; more decompositions exist.
