Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749380, here are decompositions:

23 + 8749357 = 8749380
37 + 8749343 = 8749380
43 + 8749337 = 8749380
71 + 8749309 = 8749380
137 + 8749243 = 8749380
151 + 8749229 = 8749380
173 + 8749207 = 8749380
181 + 8749199 = 8749380

Showing the first eight; more decompositions exist.
