Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463788, here are decompositions:

29 + 31463759 = 31463788
71 + 31463717 = 31463788
107 + 31463681 = 31463788
197 + 31463591 = 31463788
269 + 31463519 = 31463788
281 + 31463507 = 31463788
311 + 31463477 = 31463788
359 + 31463429 = 31463788

Showing the first eight; more decompositions exist.
