Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697864, here are decompositions:

5 + 8697859 = 8697864
13 + 8697851 = 8697864
31 + 8697833 = 8697864
41 + 8697823 = 8697864
53 + 8697811 = 8697864
61 + 8697803 = 8697864
67 + 8697797 = 8697864
73 + 8697791 = 8697864

Showing the first eight; more decompositions exist.
