Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611932, here are decompositions:

103 + 31611829 = 31611932
199 + 31611733 = 31611932
223 + 31611709 = 31611932
229 + 31611703 = 31611932
349 + 31611583 = 31611932
379 + 31611553 = 31611932
613 + 31611319 = 31611932
631 + 31611301 = 31611932

Showing the first eight; more decompositions exist.
