Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009180, here are decompositions:

17 + 1009163 = 1009180
23 + 1009157 = 1009180
41 + 1009139 = 1009180
59 + 1009121 = 1009180
83 + 1009097 = 1009180
131 + 1009049 = 1009180
173 + 1009007 = 1009180
191 + 1008989 = 1009180

Showing the first eight; more decompositions exist.
