Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610910, here are decompositions:

17 + 31610893 = 31610910
43 + 31610867 = 31610910
131 + 31610779 = 31610910
137 + 31610773 = 31610910
139 + 31610771 = 31610910
181 + 31610729 = 31610910
269 + 31610641 = 31610910
271 + 31610639 = 31610910

Showing the first eight; more decompositions exist.
