Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532666, here are decompositions:

7 + 31532659 = 31532666
13 + 31532653 = 31532666
73 + 31532593 = 31532666
79 + 31532587 = 31532666
127 + 31532539 = 31532666
229 + 31532437 = 31532666
313 + 31532353 = 31532666
337 + 31532329 = 31532666

Showing the first eight; more decompositions exist.
