Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999272, here are decompositions:

3 + 999269 = 999272
73 + 999199 = 999272
103 + 999169 = 999272
139 + 999133 = 999272
181 + 999091 = 999272
223 + 999049 = 999272
229 + 999043 = 999272
283 + 998989 = 999272

Showing the first eight; more decompositions exist.
