Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468506, here are decompositions:

7 + 31468499 = 31468506
53 + 31468453 = 31468506
59 + 31468447 = 31468506
103 + 31468403 = 31468506
107 + 31468399 = 31468506
109 + 31468397 = 31468506
137 + 31468369 = 31468506
263 + 31468243 = 31468506

Showing the first eight; more decompositions exist.
