Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534434, here are decompositions:

5 + 31534429 = 31534434
7 + 31534427 = 31534434
11 + 31534423 = 31534434
23 + 31534411 = 31534434
101 + 31534333 = 31534434
137 + 31534297 = 31534434
163 + 31534271 = 31534434
193 + 31534241 = 31534434

Showing the first eight; more decompositions exist.
