Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998222, here are decompositions:

3 + 998219 = 998222
61 + 998161 = 998222
139 + 998083 = 998222
151 + 998071 = 998222
193 + 998029 = 998222
331 + 997891 = 998222
409 + 997813 = 998222
439 + 997783 = 998222

Showing the first eight; more decompositions exist.
