Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999124, here are decompositions:

23 + 999101 = 999124
41 + 999083 = 999124
101 + 999023 = 999124
167 + 998957 = 999124
173 + 998951 = 999124
197 + 998927 = 999124
227 + 998897 = 999124
263 + 998861 = 999124

Showing the first eight; more decompositions exist.
