Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464678, here are decompositions:

29 + 31464649 = 31464678
59 + 31464619 = 31464678
61 + 31464617 = 31464678
97 + 31464581 = 31464678
101 + 31464577 = 31464678
107 + 31464571 = 31464678
131 + 31464547 = 31464678
197 + 31464481 = 31464678

Showing the first eight; more decompositions exist.
