Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532464, here are decompositions:

347 + 31532117 = 31532464
401 + 31532063 = 31532464
443 + 31532021 = 31532464
461 + 31532003 = 31532464
647 + 31531817 = 31532464
797 + 31531667 = 31532464
941 + 31531523 = 31532464
1061 + 31531403 = 31532464

Showing the first eight; more decompositions exist.
