Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464244, here are decompositions:

11 + 31464233 = 31464244
101 + 31464143 = 31464244
107 + 31464137 = 31464244
197 + 31464047 = 31464244
281 + 31463963 = 31464244
347 + 31463897 = 31464244
353 + 31463891 = 31464244
401 + 31463843 = 31464244

Showing the first eight; more decompositions exist.
