Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751380, here are decompositions:

13 + 8751367 = 8751380
31 + 8751349 = 8751380
61 + 8751319 = 8751380
199 + 8751181 = 8751380
223 + 8751157 = 8751380
229 + 8751151 = 8751380
241 + 8751139 = 8751380
283 + 8751097 = 8751380

Showing the first eight; more decompositions exist.
