Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998012, here are decompositions:

3 + 998009 = 998012
79 + 997933 = 998012
199 + 997813 = 998012
229 + 997783 = 998012
271 + 997741 = 998012
313 + 997699 = 998012
331 + 997681 = 998012
349 + 997663 = 998012

Showing the first eight; more decompositions exist.
