Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607734, here are decompositions:

17 + 31607717 = 31607734
47 + 31607687 = 31607734
311 + 31607423 = 31607734
443 + 31607291 = 31607734
647 + 31607087 = 31607734
761 + 31606973 = 31607734
887 + 31606847 = 31607734
1031 + 31606703 = 31607734

Showing the first eight; more decompositions exist.
