Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463798, here are decompositions:

19 + 31463779 = 31463798
31 + 31463767 = 31463798
109 + 31463689 = 31463798
211 + 31463587 = 31463798
271 + 31463527 = 31463798
409 + 31463389 = 31463798
571 + 31463227 = 31463798
601 + 31463197 = 31463798

Showing the first eight; more decompositions exist.
