Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611074, here are decompositions:

7 + 31611067 = 31611074
31 + 31611043 = 31611074
37 + 31611037 = 31611074
163 + 31610911 = 31611074
181 + 31610893 = 31611074
283 + 31610791 = 31611074
367 + 31610707 = 31611074
433 + 31610641 = 31611074

Showing the first eight; more decompositions exist.
