Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527960, here are decompositions:

19 + 31527941 = 31527960
29 + 31527931 = 31527960
47 + 31527913 = 31527960
73 + 31527887 = 31527960
131 + 31527829 = 31527960
173 + 31527787 = 31527960
179 + 31527781 = 31527960
251 + 31527709 = 31527960

Showing the first eight; more decompositions exist.
