Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8750400, here are decompositions:

13 + 8750387 = 8750400
23 + 8750377 = 8750400
31 + 8750369 = 8750400
37 + 8750363 = 8750400
53 + 8750347 = 8750400
59 + 8750341 = 8750400
67 + 8750333 = 8750400
79 + 8750321 = 8750400

Showing the first eight; more decompositions exist.
