Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999160, here are decompositions:

11 + 999149 = 999160
59 + 999101 = 999160
131 + 999029 = 999160
137 + 999023 = 999160
191 + 998969 = 999160
233 + 998927 = 999160
251 + 998909 = 999160
263 + 998897 = 999160

Showing the first eight; more decompositions exist.
