Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023864, here are decompositions:

7 + 1023857 = 1023864
13 + 1023851 = 1023864
31 + 1023833 = 1023864
43 + 1023821 = 1023864
113 + 1023751 = 1023864
131 + 1023733 = 1023864
167 + 1023697 = 1023864
211 + 1023653 = 1023864

Showing the first eight; more decompositions exist.
