Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606734, here are decompositions:

7 + 31606727 = 31606734
23 + 31606711 = 31606734
31 + 31606703 = 31606734
37 + 31606697 = 31606734
43 + 31606691 = 31606734
53 + 31606681 = 31606734
67 + 31606667 = 31606734
73 + 31606661 = 31606734

Showing the first eight; more decompositions exist.
