Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483924, here are decompositions:

5 + 31483919 = 31483924
11 + 31483913 = 31483924
41 + 31483883 = 31483924
47 + 31483877 = 31483924
53 + 31483871 = 31483924
83 + 31483841 = 31483924
191 + 31483733 = 31483924
233 + 31483691 = 31483924

Showing the first eight; more decompositions exist.
