Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999320, here are decompositions:

13 + 999307 = 999320
103 + 999217 = 999320
139 + 999181 = 999320
151 + 999169 = 999320
229 + 999091 = 999320
271 + 999049 = 999320
277 + 999043 = 999320
313 + 999007 = 999320

Showing the first eight; more decompositions exist.
