Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482660, here are decompositions:

17 + 31482643 = 31482660
19 + 31482641 = 31482660
29 + 31482631 = 31482660
43 + 31482617 = 31482660
47 + 31482613 = 31482660
61 + 31482599 = 31482660
73 + 31482587 = 31482660
101 + 31482559 = 31482660

Showing the first eight; more decompositions exist.
