Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 153864, here are decompositions:

23 + 153841 = 153864
47 + 153817 = 153864
101 + 153763 = 153864
107 + 153757 = 153864
131 + 153733 = 153864
163 + 153701 = 153864
223 + 153641 = 153864
241 + 153623 = 153864

Showing the first eight; more decompositions exist.
