Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472234, here are decompositions:

43 + 31472191 = 31472234
67 + 31472167 = 31472234
103 + 31472131 = 31472234
127 + 31472107 = 31472234
181 + 31472053 = 31472234
193 + 31472041 = 31472234
223 + 31472011 = 31472234
523 + 31471711 = 31472234

Showing the first eight; more decompositions exist.
