Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464470, here are decompositions:

7 + 31464463 = 31464470
19 + 31464451 = 31464470
31 + 31464439 = 31464470
43 + 31464427 = 31464470
61 + 31464409 = 31464470
73 + 31464397 = 31464470
199 + 31464271 = 31464470
277 + 31464193 = 31464470

Showing the first eight; more decompositions exist.
