Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463160, here are decompositions:

13 + 31463147 = 31463160
23 + 31463137 = 31463160
37 + 31463123 = 31463160
61 + 31463099 = 31463160
73 + 31463087 = 31463160
83 + 31463077 = 31463160
97 + 31463063 = 31463160
137 + 31463023 = 31463160

Showing the first eight; more decompositions exist.
