Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008180, here are decompositions:

23 + 1008157 = 1008180
79 + 1008101 = 1008180
137 + 1008043 = 1008180
139 + 1008041 = 1008180
149 + 1008031 = 1008180
163 + 1008017 = 1008180
167 + 1008013 = 1008180
179 + 1008001 = 1008180

Showing the first eight; more decompositions exist.
