Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611926, here are decompositions:

19 + 31611907 = 31611926
43 + 31611883 = 31611926
97 + 31611829 = 31611926
109 + 31611817 = 31611926
193 + 31611733 = 31611926
223 + 31611703 = 31611926
349 + 31611577 = 31611926
373 + 31611553 = 31611926

Showing the first eight; more decompositions exist.
