Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999172, here are decompositions:

3 + 999169 = 999172
23 + 999149 = 999172
71 + 999101 = 999172
89 + 999083 = 999172
149 + 999023 = 999172
263 + 998909 = 999172
311 + 998861 = 999172
353 + 998819 = 999172

Showing the first eight; more decompositions exist.
