Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610982, here are decompositions:

71 + 31610911 = 31610982
89 + 31610893 = 31610982
191 + 31610791 = 31610982
211 + 31610771 = 31610982
241 + 31610741 = 31610982
353 + 31610629 = 31610982
401 + 31610581 = 31610982
409 + 31610573 = 31610982

Showing the first eight; more decompositions exist.
