Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545976, here are decompositions:

17 + 31545959 = 31545976
23 + 31545953 = 31545976
53 + 31545923 = 31545976
89 + 31545887 = 31545976
227 + 31545749 = 31545976
233 + 31545743 = 31545976
239 + 31545737 = 31545976
263 + 31545713 = 31545976

Showing the first eight; more decompositions exist.
