Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483932, here are decompositions:

5 + 31483927 = 31483932
13 + 31483919 = 31483932
19 + 31483913 = 31483932
43 + 31483889 = 31483932
61 + 31483871 = 31483932
71 + 31483861 = 31483932
113 + 31483819 = 31483932
131 + 31483801 = 31483932

Showing the first eight; more decompositions exist.
