Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 985158, here are decompositions:

7 + 985151 = 985158
29 + 985129 = 985158
37 + 985121 = 985158
61 + 985097 = 985158
79 + 985079 = 985158
101 + 985057 = 985158
131 + 985027 = 985158
151 + 985007 = 985158

Showing the first eight; more decompositions exist.
