Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536620, here are decompositions:

7 + 31536613 = 31536620
13 + 31536607 = 31536620
139 + 31536481 = 31536620
223 + 31536397 = 31536620
229 + 31536391 = 31536620
307 + 31536313 = 31536620
397 + 31536223 = 31536620
433 + 31536187 = 31536620

Showing the first eight; more decompositions exist.
