Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453372, here are decompositions:

11 + 31453361 = 31453372
89 + 31453283 = 31453372
131 + 31453241 = 31453372
179 + 31453193 = 31453372
191 + 31453181 = 31453372
239 + 31453133 = 31453372
521 + 31452851 = 31453372
569 + 31452803 = 31453372

Showing the first eight; more decompositions exist.
