Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532522, here are decompositions:

181 + 31532341 = 31532522
193 + 31532329 = 31532522
199 + 31532323 = 31532522
313 + 31532209 = 31532522
409 + 31532113 = 31532522
433 + 31532089 = 31532522
601 + 31531921 = 31532522
613 + 31531909 = 31532522

Showing the first eight; more decompositions exist.
