Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611814, here are decompositions:

11 + 31611803 = 31611814
53 + 31611761 = 31611814
167 + 31611647 = 31611814
173 + 31611641 = 31611814
197 + 31611617 = 31611814
233 + 31611581 = 31611814
347 + 31611467 = 31611814
491 + 31611323 = 31611814

Showing the first eight; more decompositions exist.
