Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611722, here are decompositions:

3 + 31611719 = 31611722
13 + 31611709 = 31611722
19 + 31611703 = 31611722
139 + 31611583 = 31611722
283 + 31611439 = 31611722
421 + 31611301 = 31611722
673 + 31611049 = 31611722
811 + 31610911 = 31611722

Showing the first eight; more decompositions exist.
