Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452322, here are decompositions:

89 + 31452233 = 31452322
113 + 31452209 = 31452322
149 + 31452173 = 31452322
191 + 31452131 = 31452322
233 + 31452089 = 31452322
281 + 31452041 = 31452322
353 + 31451969 = 31452322
521 + 31451801 = 31452322

Showing the first eight; more decompositions exist.
