Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549396, here are decompositions:

5 + 31549391 = 31549396
23 + 31549373 = 31549396
59 + 31549337 = 31549396
353 + 31549043 = 31549396
443 + 31548953 = 31549396
647 + 31548749 = 31549396
653 + 31548743 = 31549396
719 + 31548677 = 31549396

Showing the first eight; more decompositions exist.
