Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998418, here are decompositions:

7 + 998411 = 998418
19 + 998399 = 998418
37 + 998381 = 998418
41 + 998377 = 998418
89 + 998329 = 998418
107 + 998311 = 998418
131 + 998287 = 998418
137 + 998281 = 998418

Showing the first eight; more decompositions exist.
