Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532706, here are decompositions:

13 + 31532693 = 31532706
19 + 31532687 = 31532706
47 + 31532659 = 31532706
53 + 31532653 = 31532706
67 + 31532639 = 31532706
109 + 31532597 = 31532706
113 + 31532593 = 31532706
167 + 31532539 = 31532706

Showing the first eight; more decompositions exist.
