Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463530, here are decompositions:

3 + 31463527 = 31463530
11 + 31463519 = 31463530
23 + 31463507 = 31463530
41 + 31463489 = 31463530
47 + 31463483 = 31463530
53 + 31463477 = 31463530
71 + 31463459 = 31463530
101 + 31463429 = 31463530

Showing the first eight; more decompositions exist.
