Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464690, here are decompositions:

41 + 31464649 = 31464690
71 + 31464619 = 31464690
73 + 31464617 = 31464690
109 + 31464581 = 31464690
113 + 31464577 = 31464690
181 + 31464509 = 31464690
197 + 31464493 = 31464690
227 + 31464463 = 31464690

Showing the first eight; more decompositions exist.
