Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482900, here are decompositions:

11 + 31482889 = 31482900
41 + 31482859 = 31482900
61 + 31482839 = 31482900
67 + 31482833 = 31482900
79 + 31482821 = 31482900
101 + 31482799 = 31482900
139 + 31482761 = 31482900
157 + 31482743 = 31482900

Showing the first eight; more decompositions exist.
