Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576432, here are decompositions:

5 + 31576427 = 31576432
23 + 31576409 = 31576432
29 + 31576403 = 31576432
59 + 31576373 = 31576432
149 + 31576283 = 31576432
179 + 31576253 = 31576432
191 + 31576241 = 31576432
233 + 31576199 = 31576432

Showing the first eight; more decompositions exist.
