Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998170, here are decompositions:

3 + 998167 = 998170
23 + 998147 = 998170
53 + 998117 = 998170
59 + 998111 = 998170
101 + 998069 = 998170
179 + 997991 = 998170
197 + 997973 = 998170
281 + 997889 = 998170

Showing the first eight; more decompositions exist.
