Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483824, here are decompositions:

5 + 31483819 = 31483824
17 + 31483807 = 31483824
23 + 31483801 = 31483824
101 + 31483723 = 31483824
227 + 31483597 = 31483824
241 + 31483583 = 31483824
271 + 31483553 = 31483824
277 + 31483547 = 31483824

Showing the first eight; more decompositions exist.
