Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599932, here are decompositions:

3 + 31599929 = 31599932
19 + 31599913 = 31599932
31 + 31599901 = 31599932
61 + 31599871 = 31599932
73 + 31599859 = 31599932
109 + 31599823 = 31599932
151 + 31599781 = 31599932
229 + 31599703 = 31599932

Showing the first eight; more decompositions exist.
