Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464468, here are decompositions:

5 + 31464463 = 31464468
17 + 31464451 = 31464468
29 + 31464439 = 31464468
41 + 31464427 = 31464468
47 + 31464421 = 31464468
59 + 31464409 = 31464468
67 + 31464401 = 31464468
71 + 31464397 = 31464468

Showing the first eight; more decompositions exist.
