Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532032, here are decompositions:

11 + 31532021 = 31532032
29 + 31532003 = 31532032
101 + 31531931 = 31532032
149 + 31531883 = 31532032
281 + 31531751 = 31532032
353 + 31531679 = 31532032
383 + 31531649 = 31532032
509 + 31531523 = 31532032

Showing the first eight; more decompositions exist.
