Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658172, here are decompositions:

11 + 8658161 = 8658172
71 + 8658101 = 8658172
113 + 8658059 = 8658172
239 + 8657933 = 8658172
269 + 8657903 = 8658172
389 + 8657783 = 8658172
401 + 8657771 = 8658172
449 + 8657723 = 8658172

Showing the first eight; more decompositions exist.
