Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610940, here are decompositions:

29 + 31610911 = 31610940
47 + 31610893 = 31610940
73 + 31610867 = 31610940
149 + 31610791 = 31610940
167 + 31610773 = 31610940
199 + 31610741 = 31610940
211 + 31610729 = 31610940
233 + 31610707 = 31610940

Showing the first eight; more decompositions exist.
