Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483914, here are decompositions:

31 + 31483883 = 31483914
37 + 31483877 = 31483914
43 + 31483871 = 31483914
53 + 31483861 = 31483914
73 + 31483841 = 31483914
107 + 31483807 = 31483914
113 + 31483801 = 31483914
181 + 31483733 = 31483914

Showing the first eight; more decompositions exist.
