Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446434, here are decompositions:

7 + 31446427 = 31446434
67 + 31446367 = 31446434
73 + 31446361 = 31446434
181 + 31446253 = 31446434
193 + 31446241 = 31446434
211 + 31446223 = 31446434
223 + 31446211 = 31446434
337 + 31446097 = 31446434

Showing the first eight; more decompositions exist.
