Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998356, here are decompositions:

3 + 998353 = 998356
83 + 998273 = 998356
113 + 998243 = 998356
137 + 998219 = 998356
239 + 998117 = 998356
347 + 998009 = 998356
383 + 997973 = 998356
467 + 997889 = 998356

Showing the first eight; more decompositions exist.
