Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482624, here are decompositions:

7 + 31482617 = 31482624
11 + 31482613 = 31482624
37 + 31482587 = 31482624
73 + 31482551 = 31482624
113 + 31482511 = 31482624
197 + 31482427 = 31482624
223 + 31482401 = 31482624
281 + 31482343 = 31482624

Showing the first eight; more decompositions exist.
