Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464654, here are decompositions:

5 + 31464649 = 31464654
37 + 31464617 = 31464654
73 + 31464581 = 31464654
83 + 31464571 = 31464654
97 + 31464557 = 31464654
107 + 31464547 = 31464654
173 + 31464481 = 31464654
191 + 31464463 = 31464654

Showing the first eight; more decompositions exist.
