Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1007864, here are decompositions:

3 + 1007861 = 1007864
7 + 1007857 = 1007864
37 + 1007827 = 1007864
97 + 1007767 = 1007864
163 + 1007701 = 1007864
181 + 1007683 = 1007864
307 + 1007557 = 1007864
337 + 1007527 = 1007864

Showing the first eight; more decompositions exist.
