Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85618, here are decompositions:

11 + 85607 = 85618
17 + 85601 = 85618
41 + 85577 = 85618
47 + 85571 = 85618
101 + 85517 = 85618
131 + 85487 = 85618
149 + 85469 = 85618
167 + 85451 = 85618

Showing the first eight; more decompositions exist.
