Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538434, here are decompositions:

23 + 31538411 = 31538434
101 + 31538333 = 31538434
107 + 31538327 = 31538434
173 + 31538261 = 31538434
227 + 31538207 = 31538434
281 + 31538153 = 31538434
293 + 31538141 = 31538434
401 + 31538033 = 31538434

Showing the first eight; more decompositions exist.
