Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532414, here are decompositions:

13 + 31532401 = 31532414
61 + 31532353 = 31532414
73 + 31532341 = 31532414
211 + 31532203 = 31532414
601 + 31531813 = 31532414
787 + 31531627 = 31532414
997 + 31531417 = 31532414
1153 + 31531261 = 31532414

Showing the first eight; more decompositions exist.
