Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740864, here are decompositions:

5 + 8740859 = 8740864
23 + 8740841 = 8740864
71 + 8740793 = 8740864
101 + 8740763 = 8740864
107 + 8740757 = 8740864
137 + 8740727 = 8740864
257 + 8740607 = 8740864
347 + 8740517 = 8740864

Showing the first eight; more decompositions exist.
