Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532524, here are decompositions:

3 + 31532521 = 31532524
17 + 31532507 = 31532524
47 + 31532477 = 31532524
263 + 31532261 = 31532524
383 + 31532141 = 31532524
461 + 31532063 = 31532524
503 + 31532021 = 31532524
521 + 31532003 = 31532524

Showing the first eight; more decompositions exist.
