Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1048158, here are decompositions:

19 + 1048139 = 1048158
29 + 1048129 = 1048158
31 + 1048127 = 1048158
107 + 1048051 = 1048158
109 + 1048049 = 1048158
131 + 1048027 = 1048158
149 + 1048009 = 1048158
151 + 1048007 = 1048158

Showing the first eight; more decompositions exist.
