Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541706, here are decompositions:

13 + 31541693 = 31541706
29 + 31541677 = 31541706
47 + 31541659 = 31541706
73 + 31541633 = 31541706
109 + 31541597 = 31541706
137 + 31541569 = 31541706
149 + 31541557 = 31541706
179 + 31541527 = 31541706

Showing the first eight; more decompositions exist.
