Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532272, here are decompositions:

3 + 31532269 = 31532272
11 + 31532261 = 31532272
53 + 31532219 = 31532272
131 + 31532141 = 31532272
251 + 31532021 = 31532272
269 + 31532003 = 31532272
389 + 31531883 = 31532272
521 + 31531751 = 31532272

Showing the first eight; more decompositions exist.
