Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576796, here are decompositions:

19 + 31576777 = 31576796
37 + 31576759 = 31576796
157 + 31576639 = 31576796
313 + 31576483 = 31576796
337 + 31576459 = 31576796
379 + 31576417 = 31576796
577 + 31576219 = 31576796
709 + 31576087 = 31576796

Showing the first eight; more decompositions exist.
