Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462008, here are decompositions:

5 + 31462003 = 31462008
29 + 31461979 = 31462008
31 + 31461977 = 31462008
47 + 31461961 = 31462008
59 + 31461949 = 31462008
89 + 31461919 = 31462008
157 + 31461851 = 31462008
167 + 31461841 = 31462008

Showing the first eight; more decompositions exist.
