Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8613180, here are decompositions:

19 + 8613161 = 8613180
31 + 8613149 = 8613180
53 + 8613127 = 8613180
73 + 8613107 = 8613180
89 + 8613091 = 8613180
137 + 8613043 = 8613180
139 + 8613041 = 8613180
179 + 8613001 = 8613180

Showing the first eight; more decompositions exist.
