Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506016, here are decompositions:

23 + 31505993 = 31506016
89 + 31505927 = 31506016
107 + 31505909 = 31506016
173 + 31505843 = 31506016
233 + 31505783 = 31506016
293 + 31505723 = 31506016
359 + 31505657 = 31506016
383 + 31505633 = 31506016

Showing the first eight; more decompositions exist.
