Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611724, here are decompositions:

5 + 31611719 = 31611724
83 + 31611641 = 31611724
107 + 31611617 = 31611724
197 + 31611527 = 31611724
251 + 31611473 = 31611724
257 + 31611467 = 31611724
383 + 31611341 = 31611724
401 + 31611323 = 31611724

Showing the first eight; more decompositions exist.
