Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565434, here are decompositions:

3 + 31565431 = 31565434
11 + 31565423 = 31565434
23 + 31565411 = 31565434
83 + 31565351 = 31565434
137 + 31565297 = 31565434
227 + 31565207 = 31565434
317 + 31565117 = 31565434
347 + 31565087 = 31565434

Showing the first eight; more decompositions exist.
