Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464510, here are decompositions:

17 + 31464493 = 31464510
29 + 31464481 = 31464510
47 + 31464463 = 31464510
59 + 31464451 = 31464510
67 + 31464443 = 31464510
71 + 31464439 = 31464510
83 + 31464427 = 31464510
89 + 31464421 = 31464510

Showing the first eight; more decompositions exist.
