Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998972, here are decompositions:

3 + 998969 = 998972
31 + 998941 = 998972
193 + 998779 = 998972
223 + 998749 = 998972
229 + 998743 = 998972
283 + 998689 = 998972
349 + 998623 = 998972
421 + 998551 = 998972

Showing the first eight; more decompositions exist.
