Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611832, here are decompositions:

3 + 31611829 = 31611832
29 + 31611803 = 31611832
71 + 31611761 = 31611832
113 + 31611719 = 31611832
173 + 31611659 = 31611832
191 + 31611641 = 31611832
251 + 31611581 = 31611832
293 + 31611539 = 31611832

Showing the first eight; more decompositions exist.
