Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458932, here are decompositions:

19 + 31458913 = 31458932
31 + 31458901 = 31458932
103 + 31458829 = 31458932
223 + 31458709 = 31458932
229 + 31458703 = 31458932
331 + 31458601 = 31458932
601 + 31458331 = 31458932
919 + 31458013 = 31458932

Showing the first eight; more decompositions exist.
