Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 985180, here are decompositions:

3 + 985177 = 985180
29 + 985151 = 985180
59 + 985121 = 985180
71 + 985109 = 985180
83 + 985097 = 985180
101 + 985079 = 985180
167 + 985013 = 985180
173 + 985007 = 985180

Showing the first eight; more decompositions exist.
