Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468636, here are decompositions:

5 + 31468631 = 31468636
47 + 31468589 = 31468636
83 + 31468553 = 31468636
107 + 31468529 = 31468636
113 + 31468523 = 31468636
137 + 31468499 = 31468636
233 + 31468403 = 31468636
239 + 31468397 = 31468636

Showing the first eight; more decompositions exist.
