Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599954, here are decompositions:

13 + 31599941 = 31599954
37 + 31599917 = 31599954
41 + 31599913 = 31599954
53 + 31599901 = 31599954
83 + 31599871 = 31599954
131 + 31599823 = 31599954
173 + 31599781 = 31599954
181 + 31599773 = 31599954

Showing the first eight; more decompositions exist.
