Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749356, here are decompositions:

13 + 8749343 = 8749356
19 + 8749337 = 8749356
47 + 8749309 = 8749356
113 + 8749243 = 8749356
127 + 8749229 = 8749356
137 + 8749219 = 8749356
149 + 8749207 = 8749356
157 + 8749199 = 8749356

Showing the first eight; more decompositions exist.
