Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464664, here are decompositions:

47 + 31464617 = 31464664
83 + 31464581 = 31464664
107 + 31464557 = 31464664
263 + 31464401 = 31464664
383 + 31464281 = 31464664
431 + 31464233 = 31464664
521 + 31464143 = 31464664
617 + 31464047 = 31464664

Showing the first eight; more decompositions exist.
