Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468484, here are decompositions:

13 + 31468471 = 31468484
31 + 31468453 = 31468484
37 + 31468447 = 31468484
241 + 31468243 = 31468484
283 + 31468201 = 31468484
337 + 31468147 = 31468484
457 + 31468027 = 31468484
547 + 31467937 = 31468484

Showing the first eight; more decompositions exist.
