Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463538, here are decompositions:

5 + 31463533 = 31463538
11 + 31463527 = 31463538
19 + 31463519 = 31463538
31 + 31463507 = 31463538
61 + 31463477 = 31463538
79 + 31463459 = 31463538
109 + 31463429 = 31463538
131 + 31463407 = 31463538

Showing the first eight; more decompositions exist.
