Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532716, here are decompositions:

23 + 31532693 = 31532716
29 + 31532687 = 31532716
227 + 31532489 = 31532716
239 + 31532477 = 31532716
599 + 31532117 = 31532716
653 + 31532063 = 31532716
1049 + 31531667 = 31532716
1193 + 31531523 = 31532716

Showing the first eight; more decompositions exist.
