Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718964, here are decompositions:

11 + 8718953 = 8718964
47 + 8718917 = 8718964
83 + 8718881 = 8718964
113 + 8718851 = 8718964
131 + 8718833 = 8718964
167 + 8718797 = 8718964
227 + 8718737 = 8718964
383 + 8718581 = 8718964

Showing the first eight; more decompositions exist.
