Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554398, here are decompositions:

37 + 31554361 = 31554398
61 + 31554337 = 31554398
157 + 31554241 = 31554398
199 + 31554199 = 31554398
277 + 31554121 = 31554398
691 + 31553707 = 31554398
727 + 31553671 = 31554398
739 + 31553659 = 31554398

Showing the first eight; more decompositions exist.
