Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1004158, here are decompositions:

17 + 1004141 = 1004158
41 + 1004117 = 1004158
101 + 1004057 = 1004158
131 + 1004027 = 1004158
227 + 1003931 = 1004158
251 + 1003907 = 1004158
269 + 1003889 = 1004158
317 + 1003841 = 1004158

Showing the first eight; more decompositions exist.
