Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474994, here are decompositions:

13 + 31474981 = 31474994
127 + 31474867 = 31474994
193 + 31474801 = 31474994
211 + 31474783 = 31474994
307 + 31474687 = 31474994
571 + 31474423 = 31474994
631 + 31474363 = 31474994
643 + 31474351 = 31474994

Showing the first eight; more decompositions exist.
