Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464462, here are decompositions:

11 + 31464451 = 31464462
19 + 31464443 = 31464462
23 + 31464439 = 31464462
41 + 31464421 = 31464462
53 + 31464409 = 31464462
61 + 31464401 = 31464462
103 + 31464359 = 31464462
181 + 31464281 = 31464462

Showing the first eight; more decompositions exist.
