Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999130, here are decompositions:

29 + 999101 = 999130
47 + 999083 = 999130
101 + 999029 = 999130
107 + 999023 = 999130
173 + 998957 = 999130
179 + 998951 = 999130
233 + 998897 = 999130
269 + 998861 = 999130

Showing the first eight; more decompositions exist.
