Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464484, here are decompositions:

3 + 31464481 = 31464484
41 + 31464443 = 31464484
83 + 31464401 = 31464484
251 + 31464233 = 31464484
347 + 31464137 = 31464484
521 + 31463963 = 31464484
563 + 31463921 = 31464484
587 + 31463897 = 31464484

Showing the first eight; more decompositions exist.
