Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40398, here are decompositions:

11 + 40387 = 40398
37 + 40361 = 40398
41 + 40357 = 40398
47 + 40351 = 40398
109 + 40289 = 40398
157 + 40241 = 40398
167 + 40231 = 40398
229 + 40169 = 40398

Showing the first eight; more decompositions exist.
