Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656372, here are decompositions:

3 + 8656369 = 8656372
5 + 8656367 = 8656372
59 + 8656313 = 8656372
89 + 8656283 = 8656372
239 + 8656133 = 8656372
281 + 8656091 = 8656372
293 + 8656079 = 8656372
353 + 8656019 = 8656372

Showing the first eight; more decompositions exist.
