Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999100, here are decompositions:

17 + 999083 = 999100
71 + 999029 = 999100
131 + 998969 = 999100
149 + 998951 = 999100
173 + 998927 = 999100
191 + 998909 = 999100
239 + 998861 = 999100
257 + 998843 = 999100

Showing the first eight; more decompositions exist.
