Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446296, here are decompositions:

43 + 31446253 = 31446296
67 + 31446229 = 31446296
73 + 31446223 = 31446296
163 + 31446133 = 31446296
199 + 31446097 = 31446296
229 + 31446067 = 31446296
313 + 31445983 = 31446296
337 + 31445959 = 31446296

Showing the first eight; more decompositions exist.
