Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453326, here are decompositions:

5 + 31453321 = 31453326
43 + 31453283 = 31453326
59 + 31453267 = 31453326
167 + 31453159 = 31453326
193 + 31453133 = 31453326
349 + 31452977 = 31453326
353 + 31452973 = 31453326
383 + 31452943 = 31453326

Showing the first eight; more decompositions exist.
