Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576856, here are decompositions:

13 + 31576843 = 31576856
79 + 31576777 = 31576856
97 + 31576759 = 31576856
277 + 31576579 = 31576856
307 + 31576549 = 31576856
373 + 31576483 = 31576856
379 + 31576477 = 31576856
397 + 31576459 = 31576856

Showing the first eight; more decompositions exist.
