Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532620, here are decompositions:

23 + 31532597 = 31532620
47 + 31532573 = 31532620
113 + 31532507 = 31532620
131 + 31532489 = 31532620
191 + 31532429 = 31532620
281 + 31532339 = 31532620
359 + 31532261 = 31532620
401 + 31532219 = 31532620

Showing the first eight; more decompositions exist.
