Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610798, here are decompositions:

7 + 31610791 = 31610798
19 + 31610779 = 31610798
157 + 31610641 = 31610798
211 + 31610587 = 31610798
229 + 31610569 = 31610798
277 + 31610521 = 31610798
409 + 31610389 = 31610798
601 + 31610197 = 31610798

Showing the first eight; more decompositions exist.
