Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576724, here are decompositions:

43 + 31576681 = 31576724
241 + 31576483 = 31576724
271 + 31576453 = 31576724
307 + 31576417 = 31576724
313 + 31576411 = 31576724
373 + 31576351 = 31576724
457 + 31576267 = 31576724
463 + 31576261 = 31576724

Showing the first eight; more decompositions exist.
