Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464404, here are decompositions:

3 + 31464401 = 31464404
7 + 31464397 = 31464404
211 + 31464193 = 31464404
337 + 31464067 = 31464404
373 + 31464031 = 31464404
463 + 31463941 = 31464404
547 + 31463857 = 31464404
577 + 31463827 = 31464404

Showing the first eight; more decompositions exist.
