Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453294, here are decompositions:

11 + 31453283 = 31453294
53 + 31453241 = 31453294
101 + 31453193 = 31453294
113 + 31453181 = 31453294
137 + 31453157 = 31453294
317 + 31452977 = 31453294
443 + 31452851 = 31453294
491 + 31452803 = 31453294

Showing the first eight; more decompositions exist.
