Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999154, here are decompositions:

5 + 999149 = 999154
53 + 999101 = 999154
71 + 999083 = 999154
131 + 999023 = 999154
197 + 998957 = 999154
227 + 998927 = 999154
257 + 998897 = 999154
293 + 998861 = 999154

Showing the first eight; more decompositions exist.
