Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542824, here are decompositions:

13 + 31542811 = 31542824
37 + 31542787 = 31542824
97 + 31542727 = 31542824
127 + 31542697 = 31542824
193 + 31542631 = 31542824
211 + 31542613 = 31542824
277 + 31542547 = 31542824
337 + 31542487 = 31542824

Showing the first eight; more decompositions exist.
