Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464446, here are decompositions:

3 + 31464443 = 31464446
7 + 31464439 = 31464446
19 + 31464427 = 31464446
37 + 31464409 = 31464446
367 + 31464079 = 31464446
379 + 31464067 = 31464446
487 + 31463959 = 31464446
619 + 31463827 = 31464446

Showing the first eight; more decompositions exist.
