Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657072, here are decompositions:

3 + 8657069 = 8657072
19 + 8657053 = 8657072
31 + 8657041 = 8657072
139 + 8656933 = 8657072
181 + 8656891 = 8657072
223 + 8656849 = 8657072
241 + 8656831 = 8657072
271 + 8656801 = 8657072

Showing the first eight; more decompositions exist.
