Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725164, here are decompositions:

5 + 8725159 = 8725164
11 + 8725153 = 8725164
17 + 8725147 = 8725164
23 + 8725141 = 8725164
31 + 8725133 = 8725164
53 + 8725111 = 8725164
61 + 8725103 = 8725164
73 + 8725091 = 8725164

Showing the first eight; more decompositions exist.
