Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656404, here are decompositions:

5 + 8656399 = 8656404
11 + 8656393 = 8656404
37 + 8656367 = 8656404
41 + 8656363 = 8656404
47 + 8656357 = 8656404
83 + 8656321 = 8656404
131 + 8656273 = 8656404
151 + 8656253 = 8656404

Showing the first eight; more decompositions exist.
