Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749152, here are decompositions:

11 + 8749141 = 8749152
19 + 8749133 = 8749152
31 + 8749121 = 8749152
103 + 8749049 = 8749152
151 + 8749001 = 8749152
163 + 8748989 = 8749152
173 + 8748979 = 8749152
179 + 8748973 = 8749152

Showing the first eight; more decompositions exist.
