Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023888, here are decompositions:

17 + 1023871 = 1023888
31 + 1023857 = 1023888
37 + 1023851 = 1023888
67 + 1023821 = 1023888
137 + 1023751 = 1023888
157 + 1023731 = 1023888
167 + 1023721 = 1023888
191 + 1023697 = 1023888

Showing the first eight; more decompositions exist.
