Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610006, here are decompositions:

13 + 31609993 = 31610006
73 + 31609933 = 31610006
157 + 31609849 = 31610006
193 + 31609813 = 31610006
229 + 31609777 = 31610006
283 + 31609723 = 31610006
313 + 31609693 = 31610006
397 + 31609609 = 31610006

Showing the first eight; more decompositions exist.
