Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731864, here are decompositions:

3 + 8731861 = 8731864
5 + 8731859 = 8731864
47 + 8731817 = 8731864
101 + 8731763 = 8731864
107 + 8731757 = 8731864
191 + 8731673 = 8731864
227 + 8731637 = 8731864
257 + 8731607 = 8731864

Showing the first eight; more decompositions exist.
