Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749168, here are decompositions:

5 + 8749163 = 8749168
17 + 8749151 = 8749168
41 + 8749127 = 8749168
47 + 8749121 = 8749168
149 + 8749019 = 8749168
167 + 8749001 = 8749168
179 + 8748989 = 8749168
347 + 8748821 = 8749168

Showing the first eight; more decompositions exist.
