Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1029180, here are decompositions:

13 + 1029167 = 1029180
23 + 1029157 = 1029180
29 + 1029151 = 1029180
41 + 1029139 = 1029180
67 + 1029113 = 1029180
71 + 1029109 = 1029180
157 + 1029023 = 1029180
167 + 1029013 = 1029180

Showing the first eight; more decompositions exist.
