Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464726, here are decompositions:

17 + 31464709 = 31464726
107 + 31464619 = 31464726
109 + 31464617 = 31464726
149 + 31464577 = 31464726
179 + 31464547 = 31464726
233 + 31464493 = 31464726
263 + 31464463 = 31464726
283 + 31464443 = 31464726

Showing the first eight; more decompositions exist.
