Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8710400, here are decompositions:

3 + 8710397 = 8710400
7 + 8710393 = 8710400
43 + 8710357 = 8710400
67 + 8710333 = 8710400
151 + 8710249 = 8710400
157 + 8710243 = 8710400
367 + 8710033 = 8710400
379 + 8710021 = 8710400

Showing the first eight; more decompositions exist.
