Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8607138, here are decompositions:

61 + 8607077 = 8607138
79 + 8607059 = 8607138
109 + 8607029 = 8607138
139 + 8606999 = 8607138
179 + 8606959 = 8607138
181 + 8606957 = 8607138
227 + 8606911 = 8607138
229 + 8606909 = 8607138

Showing the first eight; more decompositions exist.
