Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611444, here are decompositions:

5 + 31611439 = 31611444
41 + 31611403 = 31611444
103 + 31611341 = 31611444
173 + 31611271 = 31611444
257 + 31611187 = 31611444
281 + 31611163 = 31611444
307 + 31611137 = 31611444
317 + 31611127 = 31611444

Showing the first eight; more decompositions exist.
