Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463752, here are decompositions:

71 + 31463681 = 31463752
233 + 31463519 = 31463752
263 + 31463489 = 31463752
269 + 31463483 = 31463752
293 + 31463459 = 31463752
389 + 31463363 = 31463752
431 + 31463321 = 31463752
491 + 31463261 = 31463752

Showing the first eight; more decompositions exist.
