Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576676, here are decompositions:

3 + 31576673 = 31576676
37 + 31576639 = 31576676
97 + 31576579 = 31576676
127 + 31576549 = 31576676
193 + 31576483 = 31576676
199 + 31576477 = 31576676
223 + 31576453 = 31576676
409 + 31576267 = 31576676

Showing the first eight; more decompositions exist.
