Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492854, here are decompositions:

5 + 31492849 = 31492854
7 + 31492847 = 31492854
13 + 31492841 = 31492854
17 + 31492837 = 31492854
53 + 31492801 = 31492854
73 + 31492781 = 31492854
83 + 31492771 = 31492854
97 + 31492757 = 31492854

Showing the first eight; more decompositions exist.
