Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711400, here are decompositions:

13 + 8711387 = 8711400
17 + 8711383 = 8711400
23 + 8711377 = 8711400
37 + 8711363 = 8711400
41 + 8711359 = 8711400
43 + 8711357 = 8711400
53 + 8711347 = 8711400
67 + 8711333 = 8711400

Showing the first eight; more decompositions exist.
