Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64858, here are decompositions:

5 + 64853 = 64858
41 + 64817 = 64858
47 + 64811 = 64858
149 + 64709 = 64858
179 + 64679 = 64858
191 + 64667 = 64858
197 + 64661 = 64858
257 + 64601 = 64858

Showing the first eight; more decompositions exist.
