Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998078, here are decompositions:

7 + 998071 = 998078
61 + 998017 = 998078
181 + 997897 = 998078
199 + 997879 = 998078
271 + 997807 = 998078
337 + 997741 = 998078
379 + 997699 = 998078
397 + 997681 = 998078

Showing the first eight; more decompositions exist.
