Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483992, here are decompositions:

11 + 31483981 = 31483992
13 + 31483979 = 31483992
73 + 31483919 = 31483992
79 + 31483913 = 31483992
103 + 31483889 = 31483992
109 + 31483883 = 31483992
131 + 31483861 = 31483992
151 + 31483841 = 31483992

Showing the first eight; more decompositions exist.
