Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483860, here are decompositions:

19 + 31483841 = 31483860
41 + 31483819 = 31483860
53 + 31483807 = 31483860
59 + 31483801 = 31483860
61 + 31483799 = 31483860
71 + 31483789 = 31483860
101 + 31483759 = 31483860
127 + 31483733 = 31483860

Showing the first eight; more decompositions exist.
