Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8750440, here are decompositions:

11 + 8750429 = 8750440
53 + 8750387 = 8750440
71 + 8750369 = 8750440
89 + 8750351 = 8750440
107 + 8750333 = 8750440
131 + 8750309 = 8750440
191 + 8750249 = 8750440
197 + 8750243 = 8750440

Showing the first eight; more decompositions exist.
