Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483848, here are decompositions:

7 + 31483841 = 31483848
29 + 31483819 = 31483848
41 + 31483807 = 31483848
47 + 31483801 = 31483848
59 + 31483789 = 31483848
89 + 31483759 = 31483848
157 + 31483691 = 31483848
199 + 31483649 = 31483848

Showing the first eight; more decompositions exist.
