Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611056, here are decompositions:

7 + 31611049 = 31611056
13 + 31611043 = 31611056
19 + 31611037 = 31611056
163 + 31610893 = 31611056
277 + 31610779 = 31611056
283 + 31610773 = 31611056
349 + 31610707 = 31611056
487 + 31610569 = 31611056

Showing the first eight; more decompositions exist.
