Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999208, here are decompositions:

59 + 999149 = 999208
107 + 999101 = 999208
179 + 999029 = 999208
239 + 998969 = 999208
251 + 998957 = 999208
257 + 998951 = 999208
281 + 998927 = 999208
311 + 998897 = 999208

Showing the first eight; more decompositions exist.
