Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492824, here are decompositions:

23 + 31492801 = 31492824
43 + 31492781 = 31492824
47 + 31492777 = 31492824
53 + 31492771 = 31492824
67 + 31492757 = 31492824
73 + 31492751 = 31492824
127 + 31492697 = 31492824
157 + 31492667 = 31492824

Showing the first eight; more decompositions exist.
