Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611834, here are decompositions:

5 + 31611829 = 31611834
17 + 31611817 = 31611834
31 + 31611803 = 31611834
73 + 31611761 = 31611834
97 + 31611737 = 31611834
101 + 31611733 = 31611834
131 + 31611703 = 31611834
167 + 31611667 = 31611834

Showing the first eight; more decompositions exist.
