Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998212, here are decompositions:

11 + 998201 = 998212
101 + 998111 = 998212
239 + 997973 = 998212
251 + 997961 = 998212
263 + 997949 = 998212
401 + 997811 = 998212
419 + 997793 = 998212
443 + 997769 = 998212

Showing the first eight; more decompositions exist.
