Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464630, here are decompositions:

11 + 31464619 = 31464630
13 + 31464617 = 31464630
53 + 31464577 = 31464630
59 + 31464571 = 31464630
73 + 31464557 = 31464630
83 + 31464547 = 31464630
137 + 31464493 = 31464630
149 + 31464481 = 31464630

Showing the first eight; more decompositions exist.
