Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532396, here are decompositions:

43 + 31532353 = 31532396
67 + 31532329 = 31532396
73 + 31532323 = 31532396
127 + 31532269 = 31532396
193 + 31532203 = 31532396
229 + 31532167 = 31532396
283 + 31532113 = 31532396
307 + 31532089 = 31532396

Showing the first eight; more decompositions exist.
