Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998146, here are decompositions:

29 + 998117 = 998146
137 + 998009 = 998146
173 + 997973 = 998146
197 + 997949 = 998146
257 + 997889 = 998146
269 + 997877 = 998146
353 + 997793 = 998146
419 + 997727 = 998146

Showing the first eight; more decompositions exist.
