Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477924, here are decompositions:

17 + 31477907 = 31477924
41 + 31477883 = 31477924
47 + 31477877 = 31477924
53 + 31477871 = 31477924
83 + 31477841 = 31477924
113 + 31477811 = 31477924
131 + 31477793 = 31477924
173 + 31477751 = 31477924

Showing the first eight; more decompositions exist.
