Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028170, here are decompositions:

29 + 1028141 = 1028170
41 + 1028129 = 1028170
53 + 1028117 = 1028170
71 + 1028099 = 1028170
89 + 1028081 = 1028170
107 + 1028063 = 1028170
167 + 1028003 = 1028170
239 + 1027931 = 1028170

Showing the first eight; more decompositions exist.
