Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463008, here are decompositions:

29 + 31462979 = 31463008
107 + 31462901 = 31463008
131 + 31462877 = 31463008
197 + 31462811 = 31463008
251 + 31462757 = 31463008
257 + 31462751 = 31463008
359 + 31462649 = 31463008
419 + 31462589 = 31463008

Showing the first eight; more decompositions exist.
