Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1013998, here are decompositions:

5 + 1013993 = 1013998
107 + 1013891 = 1013998
179 + 1013819 = 1013998
257 + 1013741 = 1013998
269 + 1013729 = 1013998
281 + 1013717 = 1013998
311 + 1013687 = 1013998
317 + 1013681 = 1013998

Showing the first eight; more decompositions exist.
