Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464588, here are decompositions:

7 + 31464581 = 31464588
11 + 31464577 = 31464588
17 + 31464571 = 31464588
31 + 31464557 = 31464588
41 + 31464547 = 31464588
79 + 31464509 = 31464588
107 + 31464481 = 31464588
137 + 31464451 = 31464588

Showing the first eight; more decompositions exist.
