Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611846, here are decompositions:

5 + 31611841 = 31611846
17 + 31611829 = 31611846
29 + 31611817 = 31611846
43 + 31611803 = 31611846
89 + 31611757 = 31611846
109 + 31611737 = 31611846
113 + 31611733 = 31611846
127 + 31611719 = 31611846

Showing the first eight; more decompositions exist.
