Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464756, here are decompositions:

47 + 31464709 = 31464756
107 + 31464649 = 31464756
137 + 31464619 = 31464756
139 + 31464617 = 31464756
179 + 31464577 = 31464756
199 + 31464557 = 31464756
263 + 31464493 = 31464756
293 + 31464463 = 31464756

Showing the first eight; more decompositions exist.
