Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462998, here are decompositions:

19 + 31462979 = 31462998
29 + 31462969 = 31462998
67 + 31462931 = 31462998
89 + 31462909 = 31462998
97 + 31462901 = 31462998
101 + 31462897 = 31462998
109 + 31462889 = 31462998
167 + 31462831 = 31462998

Showing the first eight; more decompositions exist.
