Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991330, here are decompositions:

3 + 991327 = 991330
17 + 991313 = 991330
101 + 991229 = 991330
107 + 991223 = 991330
113 + 991217 = 991330
149 + 991181 = 991330
239 + 991091 = 991330
251 + 991079 = 991330

Showing the first eight; more decompositions exist.
