Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611956, here are decompositions:

73 + 31611883 = 31611956
127 + 31611829 = 31611956
139 + 31611817 = 31611956
199 + 31611757 = 31611956
223 + 31611733 = 31611956
283 + 31611673 = 31611956
349 + 31611607 = 31611956
373 + 31611583 = 31611956

Showing the first eight; more decompositions exist.
