Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999148, here are decompositions:

47 + 999101 = 999148
179 + 998969 = 999148
191 + 998957 = 999148
197 + 998951 = 999148
239 + 998909 = 999148
251 + 998897 = 999148
317 + 998831 = 999148
389 + 998759 = 999148

Showing the first eight; more decompositions exist.
