Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998312, here are decompositions:

31 + 998281 = 998312
151 + 998161 = 998312
229 + 998083 = 998312
241 + 998071 = 998312
283 + 998029 = 998312
349 + 997963 = 998312
379 + 997933 = 998312
421 + 997891 = 998312

Showing the first eight; more decompositions exist.
