Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453534, here are decompositions:

5 + 31453529 = 31453534
11 + 31453523 = 31453534
71 + 31453463 = 31453534
107 + 31453427 = 31453534
113 + 31453421 = 31453534
173 + 31453361 = 31453534
251 + 31453283 = 31453534
293 + 31453241 = 31453534

Showing the first eight; more decompositions exist.
