Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463710, here are decompositions:

29 + 31463681 = 31463710
191 + 31463519 = 31463710
227 + 31463483 = 31463710
233 + 31463477 = 31463710
251 + 31463459 = 31463710
281 + 31463429 = 31463710
347 + 31463363 = 31463710
389 + 31463321 = 31463710

Showing the first eight; more decompositions exist.
