Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85648, here are decompositions:

5 + 85643 = 85648
29 + 85619 = 85648
41 + 85607 = 85648
47 + 85601 = 85648
71 + 85577 = 85648
131 + 85517 = 85648
179 + 85469 = 85648
197 + 85451 = 85648

Showing the first eight; more decompositions exist.
