Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999358, here are decompositions:

29 + 999329 = 999358
71 + 999287 = 999358
89 + 999269 = 999358
137 + 999221 = 999358
257 + 999101 = 999358
389 + 998969 = 999358
401 + 998957 = 999358
431 + 998927 = 999358

Showing the first eight; more decompositions exist.
