Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468812, here are decompositions:

19 + 31468793 = 31468812
113 + 31468699 = 31468812
181 + 31468631 = 31468812
223 + 31468589 = 31468812
239 + 31468573 = 31468812
241 + 31468571 = 31468812
269 + 31468543 = 31468812
283 + 31468529 = 31468812

Showing the first eight; more decompositions exist.
