Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8756400, here are decompositions:

7 + 8756393 = 8756400
19 + 8756381 = 8756400
43 + 8756357 = 8756400
67 + 8756333 = 8756400
83 + 8756317 = 8756400
101 + 8756299 = 8756400
137 + 8756263 = 8756400
167 + 8756233 = 8756400

Showing the first eight; more decompositions exist.
