Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626280, here are decompositions:

31 + 8626249 = 8626280
37 + 8626243 = 8626280
43 + 8626237 = 8626280
139 + 8626141 = 8626280
151 + 8626129 = 8626280
181 + 8626099 = 8626280
283 + 8625997 = 8626280
307 + 8625973 = 8626280

Showing the first eight; more decompositions exist.
