Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998320, here are decompositions:

47 + 998273 = 998320
83 + 998237 = 998320
101 + 998219 = 998320
107 + 998213 = 998320
173 + 998147 = 998320
251 + 998069 = 998320
293 + 998027 = 998320
311 + 998009 = 998320

Showing the first eight; more decompositions exist.
