Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532384, here are decompositions:

31 + 31532353 = 31532384
43 + 31532341 = 31532384
61 + 31532323 = 31532384
157 + 31532227 = 31532384
181 + 31532203 = 31532384
271 + 31532113 = 31532384
313 + 31532071 = 31532384
463 + 31531921 = 31532384

Showing the first eight; more decompositions exist.
