Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576682, here are decompositions:

43 + 31576639 = 31576682
103 + 31576579 = 31576682
199 + 31576483 = 31576682
223 + 31576459 = 31576682
229 + 31576453 = 31576682
271 + 31576411 = 31576682
331 + 31576351 = 31576682
421 + 31576261 = 31576682

Showing the first eight; more decompositions exist.
