Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021164, here are decompositions:

5 + 1021159 = 1021164
7 + 1021157 = 1021164
37 + 1021127 = 1021164
41 + 1021123 = 1021164
71 + 1021093 = 1021164
73 + 1021091 = 1021164
83 + 1021081 = 1021164
97 + 1021067 = 1021164

Showing the first eight; more decompositions exist.
