Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542328, here are decompositions:

5 + 31542323 = 31542328
47 + 31542281 = 31542328
131 + 31542197 = 31542328
179 + 31542149 = 31542328
317 + 31542011 = 31542328
347 + 31541981 = 31542328
677 + 31541651 = 31542328
821 + 31541507 = 31542328

Showing the first eight; more decompositions exist.
