Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611048, here are decompositions:

5 + 31611043 = 31611048
11 + 31611037 = 31611048
19 + 31611029 = 31611048
31 + 31611017 = 31611048
37 + 31611011 = 31611048
137 + 31610911 = 31611048
181 + 31610867 = 31611048
257 + 31610791 = 31611048

Showing the first eight; more decompositions exist.
