Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482666, here are decompositions:

23 + 31482643 = 31482666
53 + 31482613 = 31482666
67 + 31482599 = 31482666
79 + 31482587 = 31482666
97 + 31482569 = 31482666
107 + 31482559 = 31482666
157 + 31482509 = 31482666
167 + 31482499 = 31482666

Showing the first eight; more decompositions exist.
