Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611046, here are decompositions:

3 + 31611043 = 31611046
17 + 31611029 = 31611046
23 + 31611023 = 31611046
29 + 31611017 = 31611046
179 + 31610867 = 31611046
317 + 31610729 = 31611046
653 + 31610393 = 31611046
683 + 31610363 = 31611046

Showing the first eight; more decompositions exist.
