Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625168, here are decompositions:

37 + 8625131 = 8625168
47 + 8625121 = 8625168
109 + 8625059 = 8625168
157 + 8625011 = 8625168
239 + 8624929 = 8625168
281 + 8624887 = 8625168
347 + 8624821 = 8625168
397 + 8624771 = 8625168

Showing the first eight; more decompositions exist.
