Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482648, here are decompositions:

5 + 31482643 = 31482648
7 + 31482641 = 31482648
17 + 31482631 = 31482648
31 + 31482617 = 31482648
61 + 31482587 = 31482648
79 + 31482569 = 31482648
89 + 31482559 = 31482648
97 + 31482551 = 31482648

Showing the first eight; more decompositions exist.
