Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566292, here are decompositions:

3 + 31566289 = 31566292
5 + 31566287 = 31566292
41 + 31566251 = 31566292
71 + 31566221 = 31566292
101 + 31566191 = 31566292
311 + 31565981 = 31566292
521 + 31565771 = 31566292
599 + 31565693 = 31566292

Showing the first eight; more decompositions exist.
