Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606892, here are decompositions:

13 + 31606879 = 31606892
139 + 31606753 = 31606892
151 + 31606741 = 31606892
181 + 31606711 = 31606892
211 + 31606681 = 31606892
241 + 31606651 = 31606892
313 + 31606579 = 31606892
349 + 31606543 = 31606892

Showing the first eight; more decompositions exist.
