Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484824, here are decompositions:

3 + 31484821 = 31484824
23 + 31484801 = 31484824
47 + 31484777 = 31484824
53 + 31484771 = 31484824
71 + 31484753 = 31484824
83 + 31484741 = 31484824
113 + 31484711 = 31484824
197 + 31484627 = 31484824

Showing the first eight; more decompositions exist.
