Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611746, here are decompositions:

13 + 31611733 = 31611746
37 + 31611709 = 31611746
43 + 31611703 = 31611746
73 + 31611673 = 31611746
79 + 31611667 = 31611746
139 + 31611607 = 31611746
163 + 31611583 = 31611746
193 + 31611553 = 31611746

Showing the first eight; more decompositions exist.
