Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464724, here are decompositions:

23 + 31464701 = 31464724
107 + 31464617 = 31464724
167 + 31464557 = 31464724
281 + 31464443 = 31464724
383 + 31464341 = 31464724
443 + 31464281 = 31464724
491 + 31464233 = 31464724
587 + 31464137 = 31464724

Showing the first eight; more decompositions exist.
