Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464498, here are decompositions:

5 + 31464493 = 31464498
17 + 31464481 = 31464498
47 + 31464451 = 31464498
59 + 31464439 = 31464498
71 + 31464427 = 31464498
89 + 31464409 = 31464498
97 + 31464401 = 31464498
101 + 31464397 = 31464498

Showing the first eight; more decompositions exist.
