Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464786, here are decompositions:

5 + 31464781 = 31464786
29 + 31464757 = 31464786
137 + 31464649 = 31464786
167 + 31464619 = 31464786
229 + 31464557 = 31464786
239 + 31464547 = 31464786
277 + 31464509 = 31464786
293 + 31464493 = 31464786

Showing the first eight; more decompositions exist.
