Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991350, here are decompositions:

7 + 991343 = 991350
23 + 991327 = 991350
37 + 991313 = 991350
89 + 991261 = 991350
127 + 991223 = 991350
149 + 991201 = 991350
163 + 991187 = 991350
179 + 991171 = 991350

Showing the first eight; more decompositions exist.
