Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483830, here are decompositions:

11 + 31483819 = 31483830
23 + 31483807 = 31483830
29 + 31483801 = 31483830
31 + 31483799 = 31483830
41 + 31483789 = 31483830
71 + 31483759 = 31483830
97 + 31483733 = 31483830
107 + 31483723 = 31483830

Showing the first eight; more decompositions exist.
