Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998126, here are decompositions:

43 + 998083 = 998126
97 + 998029 = 998126
109 + 998017 = 998126
163 + 997963 = 998126
193 + 997933 = 998126
229 + 997897 = 998126
313 + 997813 = 998126
433 + 997693 = 998126

Showing the first eight; more decompositions exist.
