Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627240, here are decompositions:

67 + 8627173 = 8627240
73 + 8627167 = 8627240
79 + 8627161 = 8627240
211 + 8627029 = 8627240
241 + 8626999 = 8627240
313 + 8626927 = 8627240
337 + 8626903 = 8627240
379 + 8626861 = 8627240

Showing the first eight; more decompositions exist.
