Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998668, here are decompositions:

17 + 998651 = 998668
107 + 998561 = 998668
131 + 998537 = 998668
197 + 998471 = 998668
239 + 998429 = 998668
257 + 998411 = 998668
269 + 998399 = 998668
431 + 998237 = 998668

Showing the first eight; more decompositions exist.
