Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532294, here are decompositions:

67 + 31532227 = 31532294
127 + 31532167 = 31532294
181 + 31532113 = 31532294
223 + 31532071 = 31532294
373 + 31531921 = 31532294
811 + 31531483 = 31532294
823 + 31531471 = 31532294
877 + 31531417 = 31532294

Showing the first eight; more decompositions exist.
