Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998420, here are decompositions:

43 + 998377 = 998420
67 + 998353 = 998420
109 + 998311 = 998420
139 + 998281 = 998420
223 + 998197 = 998420
337 + 998083 = 998420
349 + 998071 = 998420
457 + 997963 = 998420

Showing the first eight; more decompositions exist.
