Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1026180, here are decompositions:

13 + 1026167 = 1026180
37 + 1026143 = 1026180
41 + 1026139 = 1026180
53 + 1026127 = 1026180
61 + 1026119 = 1026180
79 + 1026101 = 1026180
107 + 1026073 = 1026180
137 + 1026043 = 1026180

Showing the first eight; more decompositions exist.
