Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464480, here are decompositions:

17 + 31464463 = 31464480
29 + 31464451 = 31464480
37 + 31464443 = 31464480
41 + 31464439 = 31464480
53 + 31464427 = 31464480
59 + 31464421 = 31464480
71 + 31464409 = 31464480
79 + 31464401 = 31464480

Showing the first eight; more decompositions exist.
