Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464564, here are decompositions:

7 + 31464557 = 31464564
17 + 31464547 = 31464564
71 + 31464493 = 31464564
83 + 31464481 = 31464564
101 + 31464463 = 31464564
113 + 31464451 = 31464564
137 + 31464427 = 31464564
163 + 31464401 = 31464564

Showing the first eight; more decompositions exist.
