Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463892, here are decompositions:

13 + 31463879 = 31463892
43 + 31463849 = 31463892
113 + 31463779 = 31463892
149 + 31463743 = 31463892
179 + 31463713 = 31463892
211 + 31463681 = 31463892
359 + 31463533 = 31463892
373 + 31463519 = 31463892

Showing the first eight; more decompositions exist.
