Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463888, here are decompositions:

31 + 31463857 = 31463888
61 + 31463827 = 31463888
109 + 31463779 = 31463888
199 + 31463689 = 31463888
499 + 31463389 = 31463888
571 + 31463317 = 31463888
607 + 31463281 = 31463888
619 + 31463269 = 31463888

Showing the first eight; more decompositions exist.
