Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611144, here are decompositions:

7 + 31611137 = 31611144
17 + 31611127 = 31611144
31 + 31611113 = 31611144
43 + 31611101 = 31611144
101 + 31611043 = 31611144
107 + 31611037 = 31611144
127 + 31611017 = 31611144
233 + 31610911 = 31611144

Showing the first eight; more decompositions exist.
