Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453266, here are decompositions:

17 + 31453249 = 31453266
59 + 31453207 = 31453266
73 + 31453193 = 31453266
107 + 31453159 = 31453266
109 + 31453157 = 31453266
227 + 31453039 = 31453266
293 + 31452973 = 31453266
463 + 31452803 = 31453266

Showing the first eight; more decompositions exist.
