Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724252, here are decompositions:

11 + 8724241 = 8724252
29 + 8724223 = 8724252
71 + 8724181 = 8724252
83 + 8724169 = 8724252
109 + 8724143 = 8724252
113 + 8724139 = 8724252
151 + 8724101 = 8724252
179 + 8724073 = 8724252

Showing the first eight; more decompositions exist.
