Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730864, here are decompositions:

5 + 8730859 = 8730864
7 + 8730857 = 8730864
13 + 8730851 = 8730864
17 + 8730847 = 8730864
61 + 8730803 = 8730864
67 + 8730797 = 8730864
71 + 8730793 = 8730864
83 + 8730781 = 8730864

Showing the first eight; more decompositions exist.
