Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554932, here are decompositions:

43 + 31554889 = 31554932
103 + 31554829 = 31554932
109 + 31554823 = 31554932
193 + 31554739 = 31554932
223 + 31554709 = 31554932
313 + 31554619 = 31554932
349 + 31554583 = 31554932
421 + 31554511 = 31554932

Showing the first eight; more decompositions exist.
