Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483894, here are decompositions:

5 + 31483889 = 31483894
11 + 31483883 = 31483894
17 + 31483877 = 31483894
23 + 31483871 = 31483894
53 + 31483841 = 31483894
311 + 31483583 = 31483894
317 + 31483577 = 31483894
347 + 31483547 = 31483894

Showing the first eight; more decompositions exist.
