Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610952, here are decompositions:

41 + 31610911 = 31610952
59 + 31610893 = 31610952
173 + 31610779 = 31610952
179 + 31610773 = 31610952
181 + 31610771 = 31610952
211 + 31610741 = 31610952
223 + 31610729 = 31610952
229 + 31610723 = 31610952

Showing the first eight; more decompositions exist.
