Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31580364, here are decompositions:

17 + 31580347 = 31580364
37 + 31580327 = 31580364
41 + 31580323 = 31580364
43 + 31580321 = 31580364
47 + 31580317 = 31580364
71 + 31580293 = 31580364
97 + 31580267 = 31580364
107 + 31580257 = 31580364

Showing the first eight; more decompositions exist.
