Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8610400, here are decompositions:

11 + 8610389 = 8610400
23 + 8610377 = 8610400
41 + 8610359 = 8610400
59 + 8610341 = 8610400
89 + 8610311 = 8610400
101 + 8610299 = 8610400
107 + 8610293 = 8610400
131 + 8610269 = 8610400

Showing the first eight; more decompositions exist.
