Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999178, here are decompositions:

29 + 999149 = 999178
149 + 999029 = 999178
227 + 998951 = 999178
251 + 998927 = 999178
269 + 998909 = 999178
281 + 998897 = 999178
317 + 998861 = 999178
347 + 998831 = 999178

Showing the first eight; more decompositions exist.
