Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474686, here are decompositions:

13 + 31474673 = 31474686
17 + 31474669 = 31474686
109 + 31474577 = 31474686
127 + 31474559 = 31474686
137 + 31474549 = 31474686
167 + 31474519 = 31474686
197 + 31474489 = 31474686
263 + 31474423 = 31474686

Showing the first eight; more decompositions exist.
