Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482852, here are decompositions:

13 + 31482839 = 31482852
19 + 31482833 = 31482852
29 + 31482823 = 31482852
31 + 31482821 = 31482852
53 + 31482799 = 31482852
73 + 31482779 = 31482852
109 + 31482743 = 31482852
211 + 31482641 = 31482852

Showing the first eight; more decompositions exist.
