Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534398, here are decompositions:

29 + 31534369 = 31534398
97 + 31534301 = 31534398
101 + 31534297 = 31534398
127 + 31534271 = 31534398
151 + 31534247 = 31534398
157 + 31534241 = 31534398
167 + 31534231 = 31534398
199 + 31534199 = 31534398

Showing the first eight; more decompositions exist.
