Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504836, here are decompositions:

17 + 31504819 = 31504836
37 + 31504799 = 31504836
53 + 31504783 = 31504836
89 + 31504747 = 31504836
229 + 31504607 = 31504836
263 + 31504573 = 31504836
269 + 31504567 = 31504836
383 + 31504453 = 31504836

Showing the first eight; more decompositions exist.
