Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464680, here are decompositions:

31 + 31464649 = 31464680
61 + 31464619 = 31464680
103 + 31464577 = 31464680
109 + 31464571 = 31464680
199 + 31464481 = 31464680
229 + 31464451 = 31464680
241 + 31464439 = 31464680
271 + 31464409 = 31464680

Showing the first eight; more decompositions exist.
