Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606876, here are decompositions:

29 + 31606847 = 31606876
47 + 31606829 = 31606876
149 + 31606727 = 31606876
173 + 31606703 = 31606876
179 + 31606697 = 31606876
233 + 31606643 = 31606876
293 + 31606583 = 31606876
317 + 31606559 = 31606876

Showing the first eight; more decompositions exist.
