Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656574, here are decompositions:

13 + 8656561 = 8656574
37 + 8656537 = 8656574
97 + 8656477 = 8656574
151 + 8656423 = 8656574
163 + 8656411 = 8656574
181 + 8656393 = 8656574
211 + 8656363 = 8656574
397 + 8656177 = 8656574

Showing the first eight; more decompositions exist.
