Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610852, here are decompositions:

61 + 31610791 = 31610852
73 + 31610779 = 31610852
79 + 31610773 = 31610852
211 + 31610641 = 31610852
223 + 31610629 = 31610852
271 + 31610581 = 31610852
283 + 31610569 = 31610852
313 + 31610539 = 31610852

Showing the first eight; more decompositions exist.
