Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492960, here are decompositions:

17 + 31492943 = 31492960
53 + 31492907 = 31492960
101 + 31492859 = 31492960
113 + 31492847 = 31492960
179 + 31492781 = 31492960
263 + 31492697 = 31492960
269 + 31492691 = 31492960
293 + 31492667 = 31492960

Showing the first eight; more decompositions exist.
