Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454682, here are decompositions:

13 + 31454669 = 31454682
29 + 31454653 = 31454682
31 + 31454651 = 31454682
199 + 31454483 = 31454682
241 + 31454441 = 31454682
251 + 31454431 = 31454682
293 + 31454389 = 31454682
331 + 31454351 = 31454682

Showing the first eight; more decompositions exist.
