Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473534, here are decompositions:

5 + 31473529 = 31473534
11 + 31473523 = 31473534
47 + 31473487 = 31473534
97 + 31473437 = 31473534
137 + 31473397 = 31473534
251 + 31473283 = 31473534
271 + 31473263 = 31473534
283 + 31473251 = 31473534

Showing the first eight; more decompositions exist.
