Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611874, here are decompositions:

5 + 31611869 = 31611874
23 + 31611851 = 31611874
71 + 31611803 = 31611874
113 + 31611761 = 31611874
137 + 31611737 = 31611874
227 + 31611647 = 31611874
233 + 31611641 = 31611874
257 + 31611617 = 31611874

Showing the first eight; more decompositions exist.
