Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544398, here are decompositions:

5 + 31544393 = 31544398
101 + 31544297 = 31544398
191 + 31544207 = 31544398
227 + 31544171 = 31544398
359 + 31544039 = 31544398
401 + 31543997 = 31544398
419 + 31543979 = 31544398
491 + 31543907 = 31544398

Showing the first eight; more decompositions exist.
