Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554632, here are decompositions:

13 + 31554619 = 31554632
19 + 31554613 = 31554632
61 + 31554571 = 31554632
139 + 31554493 = 31554632
199 + 31554433 = 31554632
223 + 31554409 = 31554632
271 + 31554361 = 31554632
349 + 31554283 = 31554632

Showing the first eight; more decompositions exist.
