Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482892, here are decompositions:

3 + 31482889 = 31482892
53 + 31482839 = 31482892
59 + 31482833 = 31482892
71 + 31482821 = 31482892
113 + 31482779 = 31482892
131 + 31482761 = 31482892
149 + 31482743 = 31482892
251 + 31482641 = 31482892

Showing the first eight; more decompositions exist.
