Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468584, here are decompositions:

11 + 31468573 = 31468584
13 + 31468571 = 31468584
31 + 31468553 = 31468584
41 + 31468543 = 31468584
61 + 31468523 = 31468584
67 + 31468517 = 31468584
73 + 31468511 = 31468584
113 + 31468471 = 31468584

Showing the first eight; more decompositions exist.
