Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625166, here are decompositions:

47 + 8625119 = 8625166
83 + 8625083 = 8625166
89 + 8625077 = 8625166
107 + 8625059 = 8625166
113 + 8625053 = 8625166
167 + 8624999 = 8625166
293 + 8624873 = 8625166
359 + 8624807 = 8625166

Showing the first eight; more decompositions exist.
